Variational Quantum Circuits for Quantum State Tomography
Yong Liu, Dongyang Wang, Shichuan Xue +9
Quantum state tomography is a key process in most quantum experiments. In this work, we employ quantum machine learning for state tomography. Given an unknown quantum state, it can…
Optical control of single-photon negative-feedback avalanche diode detector
Gaëtan Gras, Nigar Sultana, Anqi Huang +4
We experimentally demonstrate optical control of negative-feedback avalanche diode (NFAD) detectors using bright light. We deterministically generate fake single-photon detections…
An approach for security evaluation and certification of a complete quantum communication system
Shihan Sajeed, Poompong Chaiwongkhot, Anqi Huang +8
Although quantum communication systems are being deployed on a global scale, their realistic security certification is not yet available. Here we present a security evaluation and…
Security analysis of practical continuous-variable quantum key distribution systems under laser seeding attack
Yi Zheng, Peng Huang, Anqi Huang +2
Here, we investigate the security of the practical one-way CVQKD and CV-MDI-QKD systems under laser seeding attack. In particular, Eve can inject a suitable light into the laser di…
Sample caching Markov chain Monte Carlo approach to boson sampling simulation
Yong Liu, Min Xiong, Chunqing Wu +10
Boson sampling is a promising candidate for quantum supremacy. It requires to sample from a complicated distribution, and is trusted to be intractable on classical computers. Among…
Controlling single-photon detector ID210 with bright light
Vladimir Chistiakov, Anqi Huang, Vladimir Egorov +1
We experimentally demonstrate that a single-photon detector ID210 commercially available from ID Quantique is vulnerable to blinding and can be fully controlled by bright illuminat…
Laser damage attack against optical attenuators in quantum key distribution
Anqi Huang, Ruoping Li, Vladimir Egorov +3
Many quantum key distribution systems employ a laser followed by an optical attenuator to prepare weak coherent states in the source. Their mean photon number must be pre-calibrate…
General-purpose quantum circuit simulator with Projected Entangled-Pair States and the quantum supremacy frontier
Chu Guo, Yong Liu, Min Xiong +12
Recent advances on quantum computing hardware have pushed quantum computing to the verge of quantum supremacy. Random quantum circuits are outstanding candidates to demonstrate qua…
Practical security of continuous-variable quantum key distribution with reduced optical attenuation
Yi Zheng, Peng Huang, Anqi Huang +2
In a practical CVQKD system, the optical attenuator can adjust the Gaussian-modulated coherent states and the local oscillator signal to an optimal value for guaranteeing the secur…
Laser seeding attack in quantum key distribution
Anqi Huang, Álvaro Navarrete, Shi-Hai Sun +3
Quantum key distribution (QKD) based on the laws of quantum physics allows the secure distribution of secret keys over an insecure channel. Unfortunately, imperfect implementations…
Eavesdropper's ability to attack a free-space quantum-key-distribution receiver in atmospheric turbulence
Poompong Chaiwongkhot, Katanya B. Kuntz, Yanbao Zhang +6
The ability of an eavesdropper (Eve) to perform an intercept-resend attack on a free-space quantum key distribution (QKD) receiver by precisely controlling the incidence angle of a…
