Spectral Attack on Continuous-Variable Quantum Key Distribution Systems
Chen Gong, Mingxuan Guo, Peng Huang +2
Continuous-variable quantum key distribution (CVQKD) has attracted extensive attention due to its compatibility and low costs. However, bandwidth mismatch exists to varying degrees…
Field Demonstration of a Multi-User Continuous-Variable Quantum Access Network for Quantum-to-the-Home
Junpeng Zhang, Xu Liu, Qijun Zhang +12
Realizing scalable Quantum-to-the-Home (QTTH) faces a bottleneck: link asymmetry in broadcast continuous-variable quantum access networks (CV-QANs) hinders the selection of a globa…
Ultra-Large-Capacity Passive Quantum Access Network Powered By Single Thermal Source
Yuehan Xu, Qijun Zhang, Xiaojuan Liao +7
Quantum Key Distribution (QKD) provides secure keys for classical communications through one-time-pad (OTP) encryption with physical-law security. Advanced PON-based Classical Acce…
High-Rate Free-Space Continuous-Variable QKD with Self-Referenced Passive State Preparation
H. W. Yin, X. J. Liao, Y. H. Xu +4
Continuous-variable quantum key distribution (CVQKD) using passive state preparation (PSP) offers low-cost, high-rate secure communication. However, the existing PSP-CVQKD scheme w…
High-key-rate Fully-Passive Quantum Access Network with Thermal Source
H. W. Yin, B. D. Zhu, H. Peng +4
To accommodate classical communication systems with progressively increasing transmission rates, quantum access networks (QAN) have undergone systematic and protocol-level optimiza…
Observation of a Doubly-strange Hyperon in
BESIII Collaboration, M. Ablikim, M. N. Achasov +758
Based on a sample of events collected with the BESIII detector at BEPCII, we report the first observation of the decay $J/Ï\rightarrow K^- Σ^0…
