Quantum secure communication uses quantum mechanisms to secure classical (non-quantum) communication and is fundamental to national information security and socioeconomic development. One of the ...

A new quantum communication method uses the temporal Talbot effect to simplify high-dimensional quantum key distribution.

A quantum internet is only as useful as its reach, and in a first, researchers created more than a million qubit pairs across 100 kilometers of fiber.

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 ...

Korean researchers have successfully established a measurement protection (MP) theory that enables stable quantum key distribution (QKD) without the need for measurement correction of quantum states, ...

BEIJING, 12 February (BelTA - Xinhua) - Chinese researchers have developed the world's first large-scale quantum key distribution (QKD) network based on integrated photonic quantum chips, according to ...

As with many information security professionals, I am a proponent of the so-called “defense in depth” approach to security—using multifaceted technologies and approaches to layer defenses and minimize ...
