The entangled state generator, which is being developed at the Military University of Technology, is a Polish contribution to the work on a new, safe quantum communication based on the phenomenon of photon entanglement.
It will not be possible to “eavesdrop” the information traveling along the fiber optic cable without an immediate “setback”.
Optical fibers need new security in the age of quantum computers.
The scientists are already working on future forms of fast and secure data transfer.
Optoelectronics and chemists from the Military University of Technology intend to secure the data flow in optical fibers by building a “entangled state generator” and “national quantum code key exchange mechanism”. Quantum communication will use light quanta that have a very special property — the state of entanglement. Entanglement causes each pair of photons to behave identically, regardless of the distance between them.
The security of such transmission, quantum communication, is based on the fundamental laws of physics.
It will be possible to detect an attack on a telecommunications channel with simple optical operations.
This breakthrough technologies will allow to secure data exchange in optical fibers, as well as standard communication that will be encrypted with a quantum key. The one-time code will be a set of unique and random sequences of characters.
