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 ...
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 ...
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 ...
A new method to distribute cryptographic keys using terahertz waves could help enable secure communication in the ...
Quantum networking is an underappreciated but potentially consequential dimension of U.S.-China quantum competition.
To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.
Russian scientists have developed a software and hardware complex for secure data transmission in 4G/5G mobile networks based ...
A team of physicists has shown that quantum-encrypted keys can travel 75 miles through the same fiber-optic cable already ...
Quantum computers, systems that process and store information leveraging quantum mechanical phenomena, could eventually outperform classical computers on numerous tasks. Among other things, these ...
