Breaking the Multiplicative Overhead in Quantum Entropy Estimation
Junxiang Huang, Chenyang Li, Lu-Fan Zhang +2
The von Neumann, Tsallis, and Rényi entropies are fundamental measures of quantum information. A common estimation strategy multiplies the worst-case costs of spectral transformati…
Efficient Noisy Quantum State and Process Tomography
Chenyang Li, Shengxin Zhuang, Yukun Zhang +4
Efficiently characterizing large quantum states and processes is a central yet notoriously challenging task in quantum information science, as conventional tomography methods typic…
High-Performance Fully Passive Discrete-State Continuous-Variable Quantum Key Distribution With Local Local Oscillator
Yu Zhang, Xuyang Wang, Chenyang Li +5
We propose and demonstrate a fully passive discrete-state continuous-variable quantum key distribution (CV-QKD), which can eliminate all modulator side channels on the source side,…
Passive continuous variable quantum key distribution
Chenyang Li, Chengqiu Hu, Wenyuan Wang +2
Passive quantum key distribution (QKD) has been proposed for discrete variable protocols to eliminate side channels in the source. Unfortunately, the key rate of passive DV-QKD pro…
Resource-Efficient Real-Time Polarization Compensation for MDI-QKD with Rejected Data
Olinka Bedroya, Chenyang Li, Wenyuan Wang +3
Measurement-device-independent quantum key distribution (MDI-QKD) closes all the security loopholes in the detection system and is a promising solution for secret key sharing. Pola…
Tagging idea in continuous variable quantum key distribution and its application
Chenyang Li, Thomas Van Himbeeck, Li Qian +1
Despite tremendous theoretical and experimental progress in continuous variable (CV) quantum key distribution (QKD), its security has not been rigorously established for practical…
Simple security proofs for continuous-variable quantum key distribution with intensity fluctuating sources
Chenyang Li, Li Qian, Hoi-Kwong Lo
Quantum Key Distribution (QKD) in principle offers unconditional security based on the laws of physics. Continuous variable (CV) quantum key distribution has the potential for high…
Secure quantum communication in the presence of phase and polarization dependent loss
Chenyang Li, Marcos Curty, Feihu Xu +2
Silicon photonics holds the promise of the miniaturization of quantum communication devices. Recently, silicon chip optical transmitters for quantum key distribution (QKD) have bee…
