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…
Towards Compute-Aware In-Switch Computing for LLMs Tensor-Parallelism on Multi-GPU Systems
Chen Zhang, Qijun Zhang, Zhuoshan Zhou +10
Tensor parallelism (TP) in large-scale LLM inference and training introduces frequent collective operations that dominate inter-GPU communication. While in-switch computing, exempl…
A polychromatic continuous-variable quantum communication network enabled by optical frequency combs
Yuehan Xu, Qijun Zhang, Junpeng Zhang +11
In classical communication, the introduction of polychromatic resources has rapidly boosted classical networks' rate and scale. Quantum communication is now at a similar critical s…
High-rate self-referenced continuous-variable quantum key distribution over high-loss free-space channel
Xiaojuan Liao, Yuehan Xu, Qijun Zhang +4
The advent of quantum computers has significantly challenged the security of traditional cryptographic systems, prompting a surge in research on quantum key distribution (QKD). Amo…
