Simulating co-propagation of Quantum Key Distribution and White Rabbit Protocols
Original language description
Quantum Key Distribution (QKD) protocols offer top-tier secure communication but face challenges with noise,particularly when quantum and classical channels coexist. In fiber-optic systems, strong classical signals for dataand synchronization create noise through scattering, with inelastic scattering being the main contributor. Thisbroad-spectrum noise can overlap with quantum communication wavelengths, leading to errors and deteriorationof the quantum signal. Our study examines the theoretical coexistence limit for a 1500 nm classical synchroniza-tion signal from a White Rabbit switch and a 1320 nm quantum signal from an S-Fifteen Instruments source,identifying the maximum fiber length where the quantum signal remains clear of noise. We chose the BB84 pro-tocol for our QKD implementation, which we plan to first test in a laboratory setting without an intermediatenode. In the future, adding a node (often referred to as Charlie) would improve scalability and help managesynchronization delays.
