Unidimensional continuous-variable quantum key distribution with imperfect detector

2019

We report a method to improve the performance of unidimensional continuous-variable quantum key distribution with imperfect detector by adding a parameter-adjustable optical amplifier, where the optimal performance can approach the scenario with a perfect detector.

Financial Big Data Hot and Cold Separation Scheme Based on HBase and Redis
