Nation-states and malicious actors are collecting encrypted data so they can read it with future quantum computers. These ...

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

Once quantum computers become a commercial reality, they will change the ground rules for cryptography. Here's how quantum cryptography would work, and an explanation of the benefits and pitfalls of ...

A claimed first-of-a-kind quantum key distribution network offers 800 Gbps encryption under real-world environmental conditions and has been demonstrated to detect and defend against quantum threats.

A new type of optical fiber filled with nothing but thin air has been found to be particularly effective for carrying out quantum key distribution (QKD), a security protocol that is in principle ...
