Researchers have successfully demonstrated the UK's first long-distance ultra-secure transfer of data over a quantum communications network, including the UK's first long-distance quantum-secured ...

A network of quantum satellites that communicate with ground stations could offer a solution to enable a global quantum network. A quantum microsatellite that has been developed and launched can ...

Coherence is the degree to which waves are in phase with each other and thus have the potential to interfere predictably. It underpins coherent quantum communications, in which interference between ...
