Secure ‘quantum messages’ sent over telecoms network in breakthrough

Researchers harness quantum mechanics to create communications system that can avoid being hacked

Quantum messages travel 254 km using existing infrastructure for the first time

Quantum messages sent across a 254-km telecom network in Germany represent the first known report of coherent quantum communications using existing commercial telecommunication infrastructure.

Quantum networks have the potential to allow secure communications, such as a quantum internet. Now, a scientific team has managed to send quantum messages 254 kilometers away using a telecommunications network -of fiber optics- already existing in Germany. The Logan entry to send quantum messages to 254 kilometers with a commercial communications network was first published in Digital Process.

Quantum Messages Cover City Distances Via Telco Lines

Researchers have shown that this can be achieved without ultra-stable lasers or cryogenic cooling, potentially lowering the barrier for industry adoption of quantum networks.
