Scientists made the first ‘unhackable’ quantum video call

Following extensive testing earlier this year, China has now deployed its quantum communications work in the form of the first ever quantum-safe video call. The call, between the Chinese Academy of Sciences and the Austrian Academy of Sciences, marks...

China bounced an ‘unhackable’ quantum signal between cities

The field of quantum cryptography, which seeks to transmit encrypted information using entangled quantum particles like photons, could help lay the groundwork for tomorrow's quantum networks but it faces a significant physical hurdle: entangled photo...
