Physicists have discovered a new method for stabilizing quantum chains using crystals.

“The nitrogen-vacancy center (N-V center or NV center) is one of numerous photoluminescent point defects in diamond. It consists of a nearest-neighbor pair of a nitrogen atom, which substitutes for a carbon atom, and a lattice vacancy.” (Wikipedia, Nitrogen-vacancy center)

“NV centers enable nanoscale measurements of magnetic and electric fields, temperature, and mechanical strain with improved precision. External perturbation sensitivity makes NV centers ideal for applications in biomedicine—such as single-molecule imaging and cellular process modeling.”(Wikipedia, Nitrogen-vacancy center)

“In crystallography, a vacancy is a type of point defect in a crystal where an atom is missing from one of the lattice sites. Crystals inherently possess imperfections, sometimes referred to as crystallographic defects.” (Wikipedia, Vacancy defect)

The image of Bravais lattices explains how electrons interact around the atom. There is, of course, a ball-shaped field around atoms, but between electrons. There is also a straight energy string. Those strings are energy flows that travel between those electrons. The atom’s shell pulls those electrons into it. And that keeps electrons and atoms. In one entirety. And the energy bridges between them, the electromagnetic push between negative electrons tries to push those electrons away. 




“The seven lattice systems and their Bravais lattices in three dimensions” (Wikipedia, Bravais lattice)


In natural diamonds, the NV centers form randomly. But. There is a possibility of creating artificial NV centers. And putting them in line. This allows information to travel through that line. Those NV centers can be used as the transmitters in the quantum radars. This means that the diamonds there have the NV state line in them. Those NV-states can be used in high-resolution quantum Doppler radars. The system transmits electricity to those NV states. And then they act as the transmitting dipoles. 

In the image above, a method is introduced for stabilizing the qubit chain in the diamonds. Qubits, or their nitrogen vacancy (NV) states, are chained in the diamond.  The diamond presses that qubit chain, and keeps it in form. When information is transported into the qubit’s transmitting side, it allows the wave to travel through those NV states. In a qubit chain, the qubits form an energy staircase. There, they can transport information. Step by step. The system can adjust energy levels on those stairs. Very accurately. This means that lasers can be used to transport energy into those NV states or NV steps. The system can transport information in the static NV-state system. 




“Simplified atomic structure of the NV center”. (Wikipedia, Nitrogen-vacancy center)


When we think of this system as the tool that transports qubits through air or quantum channels, we must remember that diamond can be used as a phonon. First, the system makes the phonon. That creates the acoustic tunnel through the air. Then the information is sent to the NV states. The NV states send that wave movement into the receiver, and there, the receiving NV state starts to resonate. Another version is that the diamond takes the one NV state to its sharpest point. The system can use the corners of the pyramid-shaped diamond. To make the energy tweezers that lock the ion in front of that NV state line. Then the qubit line stores information in that NV state. And the higher energy level in that system pushes the qubit through the quantum channel. These types of systems are very interesting. They can be used to transport information in a highly secure mode. 

“Natural NV centers are randomly oriented within a diamond crystal. Ion implantation techniques can enable their artificial creation in predetermined positions as follows.” (Wikipedia, Nitrogen-vacancy center)

“Nitrogen-vacancy centers are typically produced from single substitutional nitrogen centers (called C or P1 centers in diamond literature) by irradiation followed by annealing at temperatures above 700 °C. A wide range of high-energy particles is suitable for such irradiation, including electrons, protons, neutrons, ions, and gamma photons. Irradiation produces lattice vacancies, which are a part of NV centers. Those vacancies are immobile at room temperature, and annealing is required to move them. Single substitutional nitrogen produces strain in the diamond lattice; it therefore efficiently captures moving vacancies,[producing the NV centers.” (Wikipedia, Nitrogen-vacancy center)

New records in quantum computers.




“Princeton researchers have created a superconducting qubit that stays stable more than three times longer than previous designs, marking a major leap toward practical quantum computers. Credit: Shutterstock” (ScitechDaily, Princeton’s Breakthrough Qubit Could Finally Make Quantum Computing Practical)

New quantum computers require photonic circuits to transform binary data into qubits. And also, those systems can help to control the energy use of quantum computers, and their temperatures are lower. The new quantum photonic microchip connects the light-emitting molecules. With single-mode waveguides. The photonic microchips are halfway to compact quantum computers. Photonic chips can make. New types of observation tools are being brought into reality. Things like quantum Doppler radars, where two photons orbit each other. Those photons are in quantum entanglement with other photons that are connected to the system. Two rotating photon pairs can scan the atom’s internal structures. They act like miniature Doppler radar. 

The 50-qubit quantum computer was simulated for the first time. And the Princeton researchers set a record for qubit sustainability. Those things are a big step for quantum computers. The problem with quantum computers is their ultimate power. Regular binary computers need even tens of billions of years to solve problems that the quantum computer solves in minutes. This makes it hard to create error detection for quantum computers. This record was set by using a supercomputer.  That uses an NVIDIA-chip-based architecture.

Credit: Shutterstock” (ScitechDaily, World Record Broken: 50-Qubit Quantum Computer Fully Simulated for the First Time)

The quantum computer requires simulations to create the superpositions and quantum entanglements that those systems need. Then the system makes those connections between photons. And the weakness is that. A quantum computer is much more sensitive to outside effects. Than regular electronic computers. The biggest problem with high-power electronic computers is their heat. The simulation must be delivered to the system that maintains and controls the quantum computer. And the thing that makes quantum systems complicated is that. 

Theoretically, it is possible to make static quantum entanglement. Using some ball-shaped particles. The system puts those particles into spin motion. The idea is that. They send the string from their spin axle to the receiving particle’s equator. Then receiving particle. Starts to oscillate. And send that wave movement from its spin axle or “pole”.  

Then the quantum string transports that data to the next particle’s equator. And that can form a complex quantum system. There are quantum entanglements. That forms the box-shaped structures. Those systems are hard to control. 

The system uses those simulations for adjusting the quantum computer’s internal functions. And the problem is that things like earthquakes, cosmic rays, high-energy bursts, or even gravitational waves could disturb those systems. Those non-predictable effects can cause situations. That the system makes mistakes is hard to predict. The effect can be the situation. There, the car impacts the building, where the quantum computer is. Those things make quantum computers untrustworthy in some situations. It’s impossible to predict all variables that can affect the qubit.

Magnetism and quantum computers.


"Researchers at the University of Liège have developed a groundbreaking method to rapidly generate quantum superpositions, known as NOON states, using a combination of geometry and quantum control. This innovation drastically reduces preparation time from minutes to milliseconds, opening the door to practical applications in quantum computing and ultra-precise sensors. Credit: SciTechDaily.com" (ScitechDaily, Quantum Leap: Scientists Slash Atom Superposition Time by 10,000x)

Quantum computers are complicated systems. The quantum computer uses qubits for the data-handling process. Qubits are superpositioned and entangled particles to transport information inside them. Normally those systems use superpositioned and entangled photon pairs. The system traps photons in the frame. 

And then it starts to make the superposition and entanglements. That kind of quantum entanglement is quite hard to control because photons are so weak, that gravitational waves can affect them. 

That makes those qubits a little bit unstable. In a quantum computer, the system drives information into the particle, and then superposition and entanglement start to transport information between two superpositioned and entangled particle pairs.  



"Scientists have discovered over a dozen exotic quantum states using twisted molybdenum ditelluride, potentially paving the way for magnet-free topological quantum computers. Credit: SciTechDaily.com" (ScitechDaily, The Quantum Zoo Just Got Wilder: Magnet-Free States Discovered in Twisted Crystals)


"An illustration depicts an unexpectedly strong attraction between electrons in neighboring lattice sites within a 1D chain of copper oxide, or cuprate – a material that conducts electrical current with no loss at relatively high temperatures in their 2D counterparts. In a recent study, Stanford and SLAC scientists used X-rays to examine the behavior of pairs of spinons – quasiparticles that represent an electron’s spin. This experiment provides further evidence of an unusually strong attractive force not captured by the Hubbard model, the leading theory for predicting electron behavior in solids. Authors say the model fails to explain electron dynamics in cuprates, even in simplified, one-dimensional systems.

Things like atoms and electrons would be better particles for superposition and entanglements. But their problem is: how to protect those qubits against changes in a magnetic field. If the system can protect superposition and entanglement that makes it possible to transport information between those two particles.  

The new observations about magnetism make it possible to create new fundamental states of quantum technology. What if we could make the cylinder-shaped Hall field or Hall effect and control that field? If we, or researchers, can make the Hall effect that forms a field. 

That is slight inside. They can create a tube that protects the quantum entanglement inside it. The horizontal Hall effect is possible. That thing can make a new type of protective field that denies the internal disturbance. In some wild ideas, the Hall effect field can used as a Tipler time machine, or its quantum version. 

"Scientists have observed the anomalous Hall effect in a collinear antiferromagnet, defying conventional theories by showing it can occur without magnetization, potentially revolutionizing our understanding of quantum materials. Credit: SciTechDaily.com" (ScitechDaily, Rewriting Textbooks: Physicists Discover Anomalous Hall Effect Where It Shouldn’t Exist)

In that case the high-speed spinning magnetic field around the quantum channel. The idea is that The Hall field around those nanotubes will slow the time. In those nanotubes, the data travel between two superpositioned and entangled particles. If the fast spinning field surrounds those quantum channels that should cause time dilation in the nanotube. And that gives the quantum computer more time to operate. 

Another interesting thing is magnet-free states in twisted crystals. Those magnet-free states make it possible to create electron and atomic-scale quantum entanglements. The complex system entanglements can be the key to the new types of quantum systems. Information can travel between those two complex systems through their quantum fields. 

And if the system can make quantum entanglement using electrons or atoms it makes it easier to control those qubits. But the problem is the magnetic states. The system must protect those superpositioned and entangled particles against magnetic fields and especially against changes in the magnetic fields.

New diamond qubits are game-changing.



"The diamond quantum chip used in this research. Credit: QuTech" (ScitechDaily, Quantum Computing Breakthrough Achieved With Diamond Qubits)


"Scientists at QuTech have achieved a major milestone in quantum computing by creating highly precise quantum gates on a diamond chip, hitting error rates as low as 0.001%." (ScitechDaily, Quantum Computing Breakthrough Achieved With Diamond Qubits)

"By using ultra-pure diamonds and advanced gate designs, the team overcame key challenges that have limited previous approaches. These precise gates passed rigorous testing with long sequences of operations, marking a significant step toward building scalable quantum computers." (ScitechDaily, Quantum Computing Breakthrough Achieved With Diamond Qubits)

The problem with quantum computers is the gate that controls the information flow. The qubit can involve at the same time multiple zeros and ones. When the quantum computer loads information to qubits we can think this thing is similar to the cases where the system spray paints that information to the qubit. But in that case, the system makes the 3D structure like a globe. There the mountains and hills are the zeros and ones. 

Diamond qubits make quantum computers more effective. The prime question in those systems is how to stabilize that qubit. The qubit makes quantum entanglement between two photons. And then, it starts to make data transmission between those photons. Another promising thing to make qubits is neutrons. Neutrons are bipolar particles with N/S polarity. And that makes those particles capable of operating as qubits. 

The system transmits information into the neutron's quantum field. That energy pike in the spin axle should transmit it forward. 

The problem is that the neutron is not slight enough. The main problem is to control the photon. And transmit data in it. It's possible to use diamonds. Or, nanodiamonds trap photons and then transmit information between those diamonds. In some other cases, the nanodiamonds can also use phonons to transmit information in the quantum computer. 

The nanodiamonds and phonons are tools. That can make so-called acoustic qubits possible. The acoustic qubits are like quantum organs. In that system, all nanodiamond pairs have different resonance frequencies. So each of those pairs has different impurities and different colors. 

The acoustic or phononic qubits can mimic human brains. The idea is that those nano-size diamonds act like neurons.  

One of the reasons. Why human brains are so effective is that those neurons are close to each other. 

In the same way. In acoustic quantum computers, those diamonds are close to each other. And they can be closed in the nanotubes. That protects the acoustic transmission. The system is like the radio-wave-based systems. There each radio frequency is one layer or state of the qubit. Those diamonds can also send information in the form of EM radiation. 

Those diamonds are in opposite graphene networks. Nanodiamonds are precisely opposite to each other. A laser beam forms the phonon into those diamonds. And then. That phonon transmits data between those layers and nanodiamonds. This is one vision of acoustic qubits. 

The acoustic qubit means. That there the atoms or some atomic or subatomic particles like protons and neutrons that move. 

There is the possibility. The acoustic qubit sends the proton or some other particle to the quantum channel. That particle can also carry data itself. In that model, the acoustic system just kicks the qubit forward.

How can researchers handle noise in quantum computers?



The biggest problem with quantum computers is noise. The quantum noise forms when the quantum system oscillates randomly. The random oscillation makes it impossible to control systems. That oscillation makes standing waves or non-controlled effects. 

When data travels in qubits, we can think that each state of the qubit is like a string with two positions 0, and 1. When a qubit transmits data it takes that data on it like yarn ball layers. The difference between yarn balls is that each layer is separated. Then it sends those layers to the receiver. 

Or if we think of the qubit as a ball that is like a planet we can think dayside as 1 and night side as 0. Or if we think of the qubit as a ball that is like a planet we can think dayside as 1 and night side as 0. The problem is: how to make that ball turn in the right positions at the right moment. 

 There are billions of ways to make the qubits. Or if there are energy valleys and energy hills on the particles. The energy valleys can be 0 and hills 1. The are billions of ways to make the qubit. 

In some texts, the quantum computer is described as a voltage meter. Certain voltage level gives value 1 and below that level is 0. The decibel meter or photocells can also act as measurement tools for qubits. 

The acoustic qubit can mean that the ultrasound gives a value that is 1 and the infrasound is 0. In the decibel meter, a certain sound level is 1, and below a certain sound level, the value is 0. 

This thing is like a C-cassette but it's much smaller. So the quantum computer looks a little bit like a spinning machine. The spools are photons. And the yarns are electromagnetic strings. The steel or iron wires can theoretically act as a qubit, but it requires the oscillation to be under control and this is the problem. 

The electricity travels on the surface of the wire. There is the possibility to make a quantum channel that protects electricity against the outcoming effect. So if the wire moves and data stays in a stable position on the wire that can help to solve the problem that the Hall effect or resistance causes. The problem is in that thing is this. Researchers can protect the wire against vertical disturbance. But the problem is in vertical disturbance. 

Data or information can travel only from higher, to lower energy levels. That means the other end in the quantum lines or quantum tracks must be at a higher energy level. The system must keep the transmitting side of the quantum computer at a higher energy level. And the computer must be protected against EM. And other types of radiation. The answer can be that the data will be transmitted to the quantum computer at room temperature. Then the system will be frozen and the data handling process can start. 

There is the possibility to use laser-  or acoustic beams to make the data transmission possible between transmitters and receivers. Those beams clean the route for data carriers. 

The system can form a so-called wormhole or whirl through the quantum gas. That whirl involves a vacuum that denies the scattering effect. 

Or the quantum computer must be put in the vacuum chamber there the mechanical noise that the atoms cause is minimized. Also, things like seismic waves disturb quantum computers. 

Things like the scattering effect destroy data. The hollow laser beam that travels in a nanotube can protect photons that transmit data. The main problem with laser beams is that they are not monotonic. 

Laser beams form when particles that are stressed by light send radiation. The particle must store energy before it can send radiation. So there are small breaks in the laser beam. Those breaks allow the outside energy field to fall into that quantum channel. 


Photonics and qubits.



Photonics is a new science. Researchers make some new things almost every day. To that new, interesting science that offers limitless possibilities. The two-photon technology can mean. The photonic version of the scanning tunneling microscope. The other photon is in the frame. And the other photon hovers above the object. When another photon hovers near the surface. That causes interactions in those photons' quantum field. And that makes it possible to scan the atom's internal structures. Quantum systems require the ability to see things that the system can make interactions. 

That means the system that sees the position of things like electrons makes it possible to create Rydberg states in atoms with ultimate accuracy. Another thing is that this kind of system can increase the power of the quantum data transmissions. The system can create hollow laser beams. And then shoot the photons their data is stored in this quantum channel. The quantum channel protects information in the quantum channel. 

But quantum computers can be more advanced. If the system can use superconducting wires to transport information. The information can travel in the superconducting wire. Or it can transported between two superpositioned and entangled photons that hover in that quantum field. In the last version, the quantum field protects data in the quantum channel. 

What if we create a system where the wire moves and data stand in a static place or point on the wire? The thing in room temperature quantum computers is that. 

The Hall effect or resistance destroys data in the wire. But if the system stores data in a static point and moves that point. 

That eliminates the Hall effect. So the idea is that the wire moves and the data stays in static lace in the wire. 




"The general definition of a qubit as the quantum state of a two-level quantum system." (Wikipedia, Qubit)

The quantum computer is very close to the analog computer. We can think of the superposition and quantum entanglement we can think of that system as a C-cassette-style component. The difference between this system is that the system writes data to tape. Then it transports that point to the receiver. Then the data is in the static point. The moving tape moves data to the receiver. 

It's possible to load information row to line into the C-cassettes or series of C-cassettes and then drive that data to the receiver. It is easier to use individual tape for each quantum state. Those cassettes can benefit nanotechnology. 

We can think that qubit's states are strings. Every string has values 0 and 1.  So, theoretically is possible to create a qubit using the line of microprocessors. That means the computer line can used to make the virtual quantum computer.

Quantum computers can store information in the DNA. In that chemical version, the base pairs A, T, and G, C can be 1 and 0. ( (AT) =1 and (GC)=0) or every base can be the individual state of the qubit. A=1, T=2, G=3, C=4. In that case, the pair numbers can be 1 in those states. And pairless can be zero. The electric impulse that tells if the computer will shut down. 

The system writes the data to tape. And then tape transports that point into the reader that transports data to output.  But can that kind of analog computer be the quantum computer simulation or the quantum computer that can operate at room temperature? 

There is a model where the very thin iron wires can store data. Then those iron wires move that point in them into the receiver. The idea is that the wire that moves can keep the information in its original form. The problem is that the resistance, or Hall field destroys the data structure that travels over the wire. But what if wire travels and data stands at the same point? The idea is that wire travels between two points. The writer writes data to the wire. And then the wire moves that point like a tape recorder to the receiver.

Quantum teleportation and nanotechnology brings quantum computers closer

Quantum teleportation and nanotechnology brings quantum computers closer

Nanomachines can be used as qubits

In the qubits, what are transporting data in the quantum computers has three values 0, 1 and 2. That means that those qubits can't be translated to data by simply cutting the electricity in the wires, but I will return that thing later. There are two ways to create qubits. One version is to create the molecule by using the nanotechnology.

This molecule would be a combination of the metal and some other atoms what are not conducting electricity. The mission of the atoms, what is between the metal atoms is to isolate them from each other. In this scenario, the "Y" shaped molecule would create the qubit in a very simple way.

But creating those molecules is quite difficult. One of the most promising version could be combined iron and some big sized atoms, and the magnet field would pull that molecule through the sensor, what detects the voltage or the position of that molecule.

 If one side of this molecule would touch the sensor or the gate the value of that molecule would be 0, if two heads of the molecule touch the gate, the value can be 1 and if the all heads of that molecule would touch the gate, the value of that molecule would be 3. This would be the nanotechnical version of qubits, and those molecules can be recycled.

The thing is that the molecule or later hydrogen atom must touch the gate for being registered. And that would make some problems for that kind of things. The value of the qubit would be determined with the level of voltage of those qubits, and if only one head of qubit touches the gate the voltage would be lowest. And the lowest voltage in that gate would be translated as 0.

Use of hydrogen atoms as the qubits

If we think about the short-distance quantum teleportation, we must realize that thing can move very small particles in the extremely high speed, or the speed what would ever reach before. And how this thing is connected with quantum computers. If we think the most complicated part of the quantum computers the forming qubits, the particles what are transporting data inside the computer and processors, we are facing the new opportunity for creating the system, what uses qubits as the information transporter.

The problem with qubits is that it has at least values 0,1 and 2 or even more, and the problem is that this kind of thing needs other ways to send numbers than just cutting the electricity of the wire. In normal bit computer, the system can just cut the electricity in the wire, and that causes the effect, where the break in the electricity, what takes a certain time is translated to 0. And in normal bits, there are two layers 0 and 1. But how we could create the qubit or particle, what has more levels than zero and one?

That thing would happen by using hydrogen atoms. If the atom comes to detector the electron ahead it, the atom would get value 0, if it comes to the sensor or the gate proton ahead, it would get 1 or if it comes that way, that both electron and proton would touch the sensor or gate in the same time, this data transportation particle would get value 2, what makes it operate as the qubit.

But the problem is that we cannot calculate the place of the electron when it orbits the nucleus sharp enough, that the hydrogen atom would reach the gate in a certain position. And that thing would be an extremely difficult and slow method to shoot hydrogen through the gate in the precise right time. But if we could stop the electron, while it orbits the nucleus, that thing would make possible to create the qubit. This thing means that we could simply shoot or transport the atoms through the gate by using extremely high speed, which means that the electron would not have time to move in the orbiter, while it would face the sensor.

So this sensor would be like the gate and the position of the hydrogen atom would determine the level of the qubit. This is one very interesting method to make the quantum computer, and if we could create the singularities across the microprocessor, that thing would make the moving those hydrogen atoms or qubits in the processor easy. But that thing would need little bit advantages, because of the system, where small size black holes are creating the wormholes would be hard to make.

Astronomers could have a model for why photons from GRB 221009A were at a high energy level.
