BT Group conducts Microsoft Teams call using a Quantum optical radio receiver
Gabriela Styf Sjöman, managing director, research and network strategy has claimed that BT Group has conducted a Microsoft Teams call using a quantum optical radio receiver.

“In what we believe to be the first standards compliant, mobile communications link incorporating a Rydberg state optical receiver, the 3-way call was held between London, Ipswich and Felixstowe, using EE’s 4G spectrum,” Sjöman said.

Rydberg atoms are atoms in a highly excited state in which one electron has almost sufficient energy to escape.

Sjöman said that the optical receiver BT used could boost the capability of mobile networks and is theoretically capable of providing more than 100x more sensitivity than traditional receivers.
