Abstract Semi-quantum key distribution (SQKD) is used to establish a string of shared secret keys between quantum party and classical party. Here, we report the first proof-of-principle experimental demonstration SQKD based on Mirror protocol, which most experimentally feasible equipped with time-phase encoding scheme employing method selective modulation. The experiment was performed at repetition frequency 62.5 MHz high raw rate arrived 69.8 kbps, average bit error found be 4.56% 2.78% for...
A single-photon detection system based on InGaAs SPADs is a high-precision optical measurement capable of detecting quantum-level signals. However, the afterpulsing effect when using severely limits their practical utility. The impact effects performance systems this type detector can no longer be ignored. Therefore, paper provides detailed analysis errors induced by and proposes correction method power-law model. This analyzes probability distribution model improves expressions for system’s...
Semi-quantum key distribution (SQKD) allows sharing random keys between a quantum user and classical user. However, implementing operations is challenging, posing hurdle to achieving the Single-state protocol. By using "selective modulation" method, feasibility of SQKD verified in principle. The proposal selective modulation method enables realization other protocols for SQKD. To advance experimental progress SQKD, we propose implement phase-encoded semi-quantum system based on protocol...
Abstract The high‐order sideband generation in a gently modulating optomechanical system, which consists of standard system driven by mildly amplitude modulated field (MAMF) is investigated. It found that the can be effectively optimized choosing an appropriate component number N MAMF, and this scheme generate more flatter sidebands with same input power compared conventional model. efficiency much superior to traditional scheme. challenge for high‐efficiently realizing flat optical...
