"Chip-Based QKD Achieves Higher Transmission Speeds"

Researchers have developed a Quantum Key Distribution (QKD) system based on integrated photonics that is capable of transmitting secure keys at unprecedented speeds. The proof-of-principle experiments are a significant step toward implementing this highly secure communication method in the real world. QKD is a method for supplying distant parties with secret keys for secure communication. By using the quantum properties of light to generate secure random keys for encrypting and decrypting data, the security is based on the laws of physics, as opposed to the computational complexity of current communication protocols. This article continues to discuss the QKD system based on integrated photonics that lays the groundwork for network implementation.
