To push beyond this boundary, the team developed a quantum repeater system capable of creating memory–memory entanglement between two separate nodes. By linking these nodes through entanglement ...

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to work on innovative new ways to encrypt information. One such method is ...

Quantum key distribution (QKD) exploits the intrinsic properties of quantum mechanics to enable the secure exchange of cryptographic keys between distant parties. By utilising quantum states of light, ...

Quantum communication has long promised unbreakable encryption, but the hardware has struggled to escape the lab. A new generation of laser-written glass chips is changing that equation, carving three ...

Chinese researchers have developed the world's first large-scale quantum key distribution (QKD) network based on integrated ...

In the race to secure digital infrastructure against the looming threat of quantum computing, space has emerged as an indispensable theater. Satellites, once primarily vehicles for reconnaissance and ...

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 ...

Beijing University. Chinese scientists have built the world's first large-scale quantum key distribution (QKD) network based on integrated ...

Proof-of-Concept Passes Quantum Keys from End-to-End Over Photonic Network Spanning Heart of Chicago to NW Indiana Quantum Corridor, in collaboration with Toshiba International Corporation and ...
