Quantum Key Distribution with Integrated Photonics

Quantum computing’s rapid advancement threatens current cryptography, which relies on complex problems solvable by quantum computers. This necessitates the development of “quantum-safe” technologies for future network protection. Today’s data is also at risk from “harvest now, decrypt later” attacks, where encrypted messages are stored for decryption once quantum processors are available. This is especially concerning for long-term valuable information like financial records and medical data.
