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 ...

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 ...

- The world's first successful petabit-class transmission over more than 1,000 km using standard 19-core optical fiber, achieving a transmission rate of 1.02 petabits per second over a distance of ...

In a groundbreaking scientific achievement, Indian scientists have successfully demonstrated quantum entanglement-based free-space secure communication over a distance of more than one kilometre via ...
