Scientists Harness 19th-Century Optics To Advance Quantum Encryption

A new quantum communication method uses the temporal Talbot effect to simplify high-dimensional quantum key distribution. As digital communication accelerates and cyber threats continue to rise, researchers are searching for safer ways to transmit sensitive information. One promising approach is quantum cryptography, which uses individual photons to generate encryption keys that cannot be secretly intercepted. [...]
