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 ...

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 ...

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 ...

To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.

But a newer category is beginning to mature from theoretical research into deployable infrastructure.​ Unlike QKD, which ...

A new technical paper titled “A Practical Implementation of Quantum-Derived Keys for Secure Vehicle-to-Infrastructure Communications” was published by University of Warwick. “We provide a practical ...

Russian scientists have developed a software and hardware complex for secure data transmission in 4G/5G mobile networks based ...

The new DST Task Force report on making India’s digital ecosystems quantum-safe is a product of contemplating a threat that is both long-term and urgent. Today, public-key cryptography underpins ...

A new method to distribute cryptographic keys using terahertz waves could help enable secure communication in the ...
