Bejing sets new record for quantum secure direct communication
 

Quantum Message flung over 102.2 km

Researchers in Beijing have set a new quantum secure direct communication (QSDC) world record of 102.2 km (64 miles), smashing the previous mark of 18 km (11 miles).

According to the Eurasian Times transmission speeds were extremely slow at 0.54 bits per second, but still good enough for text message and phone call encryption over a distance of 30 km (19 miles).

Research lead Long Guilu said the work will lead to hack-proof communication, as any eavesdropping attempt on a quantum line can be instantly detected.

QSDC uses the principal of entanglement to secure networks so that since entangled particles are linked, changing the property of one by measuring it will cause another to instantly change.
