A research team from Bar Ilan University in Tel Aviv has managed to implement a method of quantum communication measurement which greatly increases the rate at which quantum measurement data is transferred. Quantum encryption secrecy relies on the ability to determine if a man-in-the-middle attack (eavesdropper) has infiltrated the communication channel between two parties. The ability for the parties to maintain secrecy relies upon measurements of the quantum communication link coupled with the speed at which the measurements are transferred. Present methods utilize electrical paths – a megahertz to gigahertz bottleneck. The team replaced the electrical method with an optical method which provides a multi-fold speed increase for the data transfer in comparison to the electrical method.
