Scientists achieve first intercity quantum key distribution with deterministic single-photon source

Conventional encryption methods rely on complex mathematical algorithms and the limits of current computing power. However, with the rise of quantum computers, these methods are becoming increasingly vulnerable, necessitating quantum key distribution (QKD). Conventional encryption methods rely on complex mathematical algorithms and the limits of current computing power.
