Optical Delay Lines in Quantum Key Distribution (QKD): Synchronization Challenges

Quantum Key Distribution (QKD) enables ultra-secure communication by leveraging the principles of quantum mechanics to exchange cryptographic keys. A critical component in many QKD systems is the optical delay line (ODL), which introduces precise time delays to synchronize photons or compensate for path-length differences. However, implementing ODLs in QKD presents several synchronization...
