A quantum primality test with order finding
Alvaro Donis-Vela, Juan Carlos Garcia-Escartin
Determining whether a given integer is prime or composite is a basic task in number theory. We present a primality test based on quantum order finding and the converse of Fermat's…
Continuous-variable measurement-device-independent quantum key distribution with virtual photon subtraction
Yijia Zhao, Yi-Chen Zhang, Bingjie Xu +2
The method of improving the performance of continuous-variable quantum key distribution protocols by post-selection has been recently proposed and verified. In continuous-variable…
High speed error correction for continuous-variable quantum key distribution with multi-edge type LDPC code
Xiangyu Wang, Yi-Chen Zhang, Song Yu +1
Error correction is a significant step in postprocessing of continuous-variable quantum key distribution system, which is used to make two distant legitimate parties share identica…
Light Source Monitoring in Quantum Key Distribution with Single Photon Detector at Room Temperature
Gan Wang, Zhengyu Li, Yucheng Qiao +3
Photon number resolving monitoring is a practical light source monitoring scheme in QKD systems, which reduces the impacts from untrusted sources effectively. This scheme requires…
Continuous-variable QKD over 50km commercial fiber
Yi-Chen Zhang, Zhengyu Li, Ziyang Chen +18
The continuous-variable version of quantum key distribution (QKD) offers the advantages (over discrete-variable systems) of higher secret key rates in metropolitan areas as well as…
High Speed Continuous Variable Source-Independent Quantum Random Number Generation
Bingjie Xu, Ziyang Chen, Zhengyu Li +5

Xiangyu Wang, Yi-Chen Zhang, Zhengyu Li +3
Information reconciliation protocol has a significant effect on the secret key rate and maximal transmission distance of continuous-variable quantum key distribution (CV-QKD) syste…
Computing quopit Clifford circuit amplitudes by the sum-over-paths technique
Dax Enshan Koh, Mark D. Penney, Robert W. Spekkens
By the Gottesman-Knill Theorem, the outcome probabilities of Clifford circuits can be computed efficiently. We present an alternative proof of this result for quopit Clifford circu…
