Imagine a receiver antenna without any metal, and therefore no thermal noise floor.
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.
Theoretically capable of providing circa 100x more sensitivity than traditional receivers, the optical receiver could boost the capability of mobile networks, creating superior ‘edge of cell’ site coverage.
This first step shows how quantum-based radio technology is steadily moving closer to real world application.
A very exciting Teams call indeed!
