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…
Robust and cost-effective quantum network using Kramers-Kronig receiver
Xu Liu, Tao Wang, Junpeng Zhang +5
The quantum internet holds the potential to facilitate applications that are fundamentally inaccessible to the classical internet. Among its most prominent applications is quantum…
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…
