Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution". In quantum communication, the participating parties can detect any attempt at eavesdropping by resorting to the fundamental principle of quantum mechanics - a measurement affects the measured quantity. Thus, the mere existence of an eavesdropper can be detected by identifying the traces that his measurements of the communication channel leave behind.

The major drawback of quantum communication today is the slow speed of data transfer, which is limited by the speed at which the parties can perform quantum measurements.

Researchers at Bar-Ilan University have devised a method that overcomes this "speed limit", and enables an increase in the rate of data transfer by more than 5 orders of magnitude! Their findings were published today in the journal Nature Communications.
