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…
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…
Improvement of two-way continuous-variable quantum key distribution with virtual photon subtraction
Yijia Zhao, Yi-Chen Zhang, Zhengyu Li +2
We propose a method to improve the performance of two-way continuous-variable quantum key distribution protocol by virtual photon subtraction. The Virtual photon subtraction implem…
Finite-size analysis of continuous-variable measurement-device-independent quantum key distribution
Xueying Zhang, Yi-Chen Zhang, Yijia Zhao +3
We study the impact of the finite-size effect on the continuous-variable measurement-device-independent quantum key distribution (CV-MDI QKD) protocol, mainly considering the finit…
Numerical simulation of the optimal two-mode attacks for two-way continuous-variable quantum cryptography in reverse reconciliation
Yi-Chen Zhang, Zhengyu Li, Yijia Zhao +2
We analyze the security of the two-way continuous-variable quantum key distribution protocol in reverse reconciliation against general two-mode attacks, which represent all accessi…
Efficient rate-adaptive reconciliation for continuous-variable quantum key distribution
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…
