Time-Bin Superposition Methods for DPS-QKD
Time-Bin Superposition Methods for DPS-QKD
Key generation efficiency, and security, in differential phase-shift quantum key distribution (DPS-QKD) improve with an increase in the number of optical delays or time-bin superpositions. We demonstrate the implementation of superposition states using time-bins, with two different approaches. In Type-A, we use an optical pulse and create superposition states with …
