Quantum key distribution (QKD) enables two parties to establish a shared secret key over an insecure channel with security guaranteed by the laws of quantum mechanics. Protocols such as BB84 and its ...

MicroCloud Hologram Inc. has announced a groundbreaking proposal for a high-dimensional quantum key distribution (QKD) protocol that utilizes quantum Fourier transform and quantum-controlled NOT gate ...

Quantum key agreement (QKA) protocols enable two or more remote parties to establish a shared secret key by exploiting fundamental quantum properties. Unlike quantum key distribution, in which one ...

In the era of instant data exchange and growing risks of cyberattacks, scientists are seeking secure methods of transmitting information. One promising solution is quantum cryptography—a quantum ...

Continuous-variable quantum cryptography has emerged as a significant branch of quantum cryptography, with continuous-variable quantum key distribution (CVQKD) at its core. However, compared to ...

As part of the QuNET project, researchers have demonstrated how quantum key distribution works reliably via hybrid and mobile channels. The results are milestones for sovereign, quantum-secured ...

The ability to send quantum information securely, known as quantum key distribution, is one of the most practical (if difficult) applications of quantum science. A new study demonstrates the ...
