Continuous-variable quantum cryptography has emerged as a significant branch of quantum cryptography, with continuous-variable quantum key ...

Quantum Key Distribution for a Post-Quantum World Quantum Key Distribution for a Post-Quantum World. New versions of QKD use separate wavelengths on the same fiber, improving cost and efficiency ...

Application security expert Michael Cobb explains how quantum key distribution works, and whether it is a viable method for improving the security of smartphones and tablets.

Quantum key distribution systems are already commercially available, but have only limited uses as they employ attenuated lasers and have a range of up to 300km in optical fibre cables.

A claimed first-of-a-kind quantum key distribution network offers 800 Gbps encryption under real-world environmental conditions and has been demonstrated to detect and defend against quantum threats.

Quantum key distribution using quantum dot single-photon emitting diodes in the red and near infrared spectral range. Applied physics at the University of Wuerzburg.

Quantum key distribution makes use of the laws of physics to provide a guaranteed level of security. Boiled down to its essential components, quantum systems must be measured to determine their state.

Multi-party quantum key distribution paves the way for quantum-secure conference calls. Although the Toshiba system is still a prototype, members of the team are enthusiastic about the progress their ...

It is based on quantum key distribution (QKD), which is a method of sharing encryption keys between two parties that can be used to encrypt and decrypt messages. This promises communication ...

Quantum key distribution Researchers at Heriot-Watt University in Edinburgh, UK generated a secure key containing over a million bits and used it to securely share an image between four users in the ...
