Intercontinental video call sets distance record for cryptography via entangled photons
During the world’s first telephone call in 1876, Alexander Graham Bell summoned his assistant from the other room, stating simply, “Mr. Watson, come here. I want to see you.” In 2017, scientists testing another newfangled type of communication were a bit more eloquent. “It is such a privilege and thrill to witness this historical moment with you all,” said Chunli Bai, president of the Chinese Academy of Sciences in Beijing, during the first intercontinental quantum-secured video call.
The more recent call, between researchers in Austria and China, capped a series of milestones reported in 2017 and made possible by the first quantum communications
