Crystals that can trap light inside them are exciting tools. If optical crystals will not conduct light away from inside them that rises their energy level until they explode. However, if the researchers can control the crystal's ability to transfer light away from inside them that makes it possible to use those crystals as data storage and invisibility systems. 

Those optical crystals can store light for quantum components. Or they can be used to store light and information for night-time use. In visions. Is possible to store light in the crystal. And then at the right moment aim it at the light detector. 

If researchers can control that process, it is possible to create new optical mass memories. For the right function. Optical mass memories require that the crystal can keep information in its form. If that light that carries information cannot stay in its original form that causes the loss of the data. There are small mirrors that can reflect 100% radiation that hits them. 

In those systems, light jumps between mirrors but the problem is that the system must freeze at a very low temperature. That removes oscillation from the system and helps to keep information in its form. The optical USB stick is like a miniature laser there are light jumps between those two mirrors. The laser writes data to that beam. And when the system needs to read that data another mirror will open. Then the beam transports that data into the photovoltaic cell. 

Those optical mass memories can revolutionize data security. The problem is how to control the reflection in the optical mass memory. And one of the answers can be those optical crystals. 

The optical crystal that traps light in it can also act as an invisibility system. The system can trap light in those crystals and then conduct it in the desired direction. That makes it possible to aim reflection and information out from the observer. Maybe in the future, those optical crystals can make those things. If those optical crystals can aim light into the aircraft's body that makes the aircraft look like a shadow.

The tractor beams and optical tweezers are big tools for nanotechnology and quantum systems.

MIT researchers developed a tractor beam. That system can capture the cell and move it from one place to another. The tractor beams are acoustic, electromagnetic, or optical systems that can capture elementary particles or more complicated things and move them without touching their environment. 

Those systems can make it possible to move complex structures between two places. The problem is that if those complicated molecules touch something. They lose their polarity. That destroys the structure. In nanotechnology, the system must create complicated atomic and molecular structures. Those structures are glued using ion, anion, and neutral atom bonds. 

"In a groundbreaking experiment at the Technion Faculty of Physics, researchers demonstrated the transfer of atoms via quantum tunneling using optical tweezers." (ScitechDaily, Quantum Tunneling Breakthrough: Technion Scientists Move Atoms With Precision)

Quantum tunneling opens new routes to communication and other things.

Theoretically is possible to tunnel even people through the walls. The problem is how to keep the complex structures in the human body in one entirety.  The system must raise energy levels in all particles in the human body at the same moment. That denies the shockwave from the human body and keeps it in one form. 

Then the system must surround the people who want to transfer the power field that is a higher energy level than the particles inside it. That keeps the person in one piece. Maybe that thing is possible someday in the future. 

Researchers moved atoms with ultimate precision. Using optical tweezers for that operation. That is the breakthrough in quantum tunneling. This is a big breakthrough because the system transported the complex structure through the barrier. The system used optical tweezers to manipulate neutral atoms. 

This technology can allow developers to create quantum computers that can transport qubits through the barrier. That is one tool that can make information safer than it has been before. Quantum tunneling makes it possible to transport particles through barriers like walls without making holes in them can be the system that makes breakthroughs in cancer treatment. 

The system can send ions or atoms or other particles through tissue and then stop it at the right point. The ions or other particles release now their energy and that thing can destroy the cancer cells.

"A simulation of a wave packet incident on a potential barrier. In relative units, the barrier energy is 20, greater than the mean wave packet energy of 14. A portion of the wave packet passes through the barrier." (Wikipedia, Quantum tunnelling)

But from those futuristic thoughts to this day. 

Quantum tunneling can make the ultimate stun or even very dangerous systems possible. The ion cannon can shoot ions through the air. 

And when the ion stops it sends a light flash.  That makes them hard to control. The light flash is the energy impulse. That can destroy complicated molecules. And that is bad for nanotechnology and complicated molecular structures. 

However, the ability to move neutral atoms through the air makes the optical system more advanced than traditional ion cannons are.  That system makes it possible to move single atoms and that is a big thing for nanotechnology. 

The system can make it possible to send even uranium ions or atoms through the air. Quantum tunneling can make it possible to create an antimatter system that can transport antimatter through air or walls. 

That thing makes it possible to create the antimatter cannons. The system requires that the optical system makes a vacuum channel through the air and when some particle moves in that channel it cannot interact with material.
