Breaking the Rate-Loss Bound of Quantum Key Distribution with Asynchronous Two-Photon Interference
Twin-field quantum key distribution can overcome the secret key capacity of repeaterless quantum key distribution via single-photon interference. However, to compensate for the channel fluctuations and lock the laser fluctuations, the techniques of phase tracking and phase locking are indispensable...
