Chip-based quantum key distribution (2015, methodology): “Finally, the DPS protocol [23] encodes information within the relative phase, 0 and π, of a train of photon pulses generated from the temporally modulated CW laser.”
Practical challenges in quantum key distribution (2016, unknown): “86,87 RR-DPS-QKD .”
Quantum key distribution with entangled photon sources (2007, methodology): “Other than decoy state method, there are other approaches to enhance the performance of the coherent state QKD, such as QKD with strong reference pulses [35, 36] and differential-phase-shift QKD [37].”
The Impact of Quantum Computing on Present Cryptography (2018, background): “Distributed phase reference coding protocols: • Differential Phase Shift (DPS) Quantum Key Distribution (QKD) protocol [46, 47] - uses a single photon in superposition state of three basis kets, where the phase difference between two sequential pulses carries bit information.”
