High speed quantum key distribution system

Web1 day ago · “But in modern systems, the speed of the detectors and the post-processing become the limiting factor for high secret key rates in QKD.” These key rates control the speed at which communicating parties can exchange a secure quantum key. Higher key rates enable users to exchange more information – both more securely, and at higher … WebQuantum key distribution system The QKD system is composed of two 19 inch rack units running a phase encoded BB84 protocol with efficient basis selection and decoy states in the finite key size regime 14. The QKD transmitter uses pulses at a wavelength of 1547.72 nm and an average intensity of 0.4 photons/pulse for the signal states.
