Researchers are the first time detected excitons.

Excitons are neutral quasiparticles. In the image above this text introduces excitons in the topological insulator. Excitons are ring-shaped structures. And they would be useful for loading data in electrons. At the quantum communication systems. Excitons are electron and electron holes that orbit each other. And producing this type of quasiparticle will make it easier to create qubits for quantum computers. 

There is the possibility that excitons are used as the antenna that aims data in a certain direction. The exciton can also act as quantum entanglement. The electromagnetic fields around excitons can superposition and entangled. Or an electron can superposition with that hole. So in that case, the system can make quantum entanglement inside the exciton.

The light-driven electronics are the next-generation tools for multiple purposes. 

Technology, where photons are pushing electrons, makes it possible to create lightweight and very powerful particle accelerators. But that kind of system also allows transmitting data in the system with very high accuracy. 

The photon-pushing electrons can use to transmit data between quantum and binary computer systems. The ability to push electrons by using photons makes it possible. That data stored in electrons keeps its form. 

But the ability to push electrons by using photons also makes it possible to create lightweight cathode or ion motors. In those systems, the photons are pushing electrons to the rocket engine. There the electrons can impact ions like protons. These kinds of systems can make spacecraft travel at a very high speed. 

In some versions, the electrons are accelerated in the chamber against the front wall of the engine. This thing gives the impact energy to the front wall of the ion or cathode engine. And that thing acts like a sail. The idea is taken from the Donald Duck magazines where a blower pushes air against the sail. And that thing makes the ship travel forward. 

The electrons that are pushed by photons are also usable for space weapons. Things like lightweight ion cannons can use this technology. This kind of technology can use to create the next-generation antimatter. The electron can be driven against a thin gold layer that turns it into a positron. 

The antimatter can use as rocket fuel. It can also use in particle accelerators for making extremely high energy levels. But antimatter can also use as a light element for lasers. In those laser systems, antimatter annihilation happens around the laser element.
