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…
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
As a fundamental phenomenon in nature, randomness has a wide range of applications in the fields of science and engineering. Among different types of random number generators (RNG)…
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…
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…
