The ability to manipulate electrons with lasers is important for nano- and quantum technology.

"By using ultrafast lasers, researchers have observed electrons moving in perfect sync inside particles smaller than a nanometer. This breakthrough unlocks new ways to manipulate light and electrons, paving the way for next-generation technology."

Ultra-fast laser impulses manipulated electrons in the C^60 fullerene molecules. That thing opened a new vision of chemistry. Laser systems are good tools for dosing energy impulses to the object. In ultra-cold atoms, laser systems can be used to manipulate energy levels with very high accuracy. Researchers observed how ultra-fast laser impulses excited electrons around atoms. 

And that opens the path to observing things whose diameter is sub-nanometer scale. The problem with very small objects is that. Things like electron microscopes and scanning laser microscopes have limits on the diameter of the structures that send radiation. Another problem is. 

How to make a system that makes reflections from that radiation? The ability to scan 3D structures is important in nanotechnology. And one of the things that could help this problem is the system that puts electrons hover in the fullerene. Then the system must inject energy impulses into the electron. That causes that electron to send energy impulses that can be used to observe this kind of structure.

The ability to freeze electrons in a certain position makes it possible to create superposition and entanglement in a certain point of the atoms. The idea is that when an electron releases its energy it sends a photon. If the system can trap photon pairs on the opposite sides of the atom, and then put those photon pairs against each other, that can make it possible to create the quantum network where superpositioned quantum entanglements transmit information between atoms. 

The information travels in chained superpositions and the molecular bonds can protect those quantum entanglements. The system that can trap photons in a certain position in the atom's quantum fields can make a revolution in quantum computing. And if the system can control the atom's spin and those photon's or quantum dot's position that makes it possible that the quantum dot takes information to the atom's shell. Then system turns the atom around and that quantum dot resends data to the next atom.

The light-assisted atomic collisions can help researchers advance the research of optical tweezers. In those tests atoms are frozen in a very low temperature makes it easier to control the oscillation.  The optical tweezers can transfer atoms with very high accuracy. And that can advance nanotechnology. The optical tweezers can also move atoms close together. Then the system can low energy lightwaves to observe how chemical bonds form in reactions between those individual atoms. That thing allows us to crack the codes of how the chemical bonds are forming. 

Light-assisted atom collisions are also tools that can be used for research the new ultra-heavy isotopes. The optical tweezers or crossing laser beams can drive other atoms against each other and then researchers can hope that their nuclei melt together. The problem with heavy isotope collisions is that if the system uses too much energy that thing breaks the isotope. And the laser beam's energy is easier to control than regular particle accelerators' collision energy.
