Experimental Mode-Pairing Measurement-Device-Independent Quantum Key Distribution without Global Phase Locking

Experimental Mode-Pairing Measurement-Device-Independent Quantum Key Distribution without Global Phase Locking In the past two decades, quantum key distribution networks based on telecom fibers have been implemented on metropolitan and intercity scales. One of the bottlenecks lies in the exponential decay of the key rate with respect to the transmission distance. Recently proposed schemes mainly focus on achieving longer distances by creating a long-arm single-photon interferometer over two com...
