Sending-or-not-sending twin-field quantum key distribution with discrete-phase-randomized weak coherent states

In many security proofs of quantum key distribution, the random phases of coherent states are assumed to be continuously modulated. However, in practice, we can only take discrete phase randomization to coherent-state sources. In this paper, we study the sending-or-not-sending (SNS) protocol with di...
