Hollow-Core Fiber for Long-Span Optical Frequency Transfer: Improved Instability and Extended Single-Span Reach
Qian Zhou, Ru Yuan, Xiang Zhang +12
Phase-coherent optical frequency transfer is essential for optical clock networking, relativistic geodesy, and distributed precision metrology. However, realizing coherent optical…
Security Enhancement of Quantum Noise Stream Cipher Based on Probabilistic Constellation Shaping
Sheng Liu, Shuang Wei, Wei Wang +10
We propose a QNSC pre-coding scheme based on probabilistic shaping of the basis, to reduce the probability of ciphertext bits that are easier to be intercepted. Experiment results…
1-Tb/s/λ Transmission over Record 10714-km AR-HCF
Dawei Ge, Siyuan Liu, Qiang Qiu +12
We present the first single-channel 1.001-Tb/s DP-36QAM-PCS recirculating transmission over 73 loops of 146.77-km ultra-low-loss & low-IMI DNANF-5 fiber, achieving a record transmi…
Long-distance transmission of quantum key distribution coexisting with classical optical communication over weakly-coupled few-mode fiber
Bi-Xiao Wang, Yingqiu Mao, Lei Shen +10
Quantum key distribution (QKD) is one of the most practical applications in quantum information processing, which can generate information-theoretical secure keys between remote pa…
Design of Angular-offset Interstitial-Tube- Assisted Hollow-Core Fibers with Ultrahigh Mode Purity and Ultralow Loss
Hao Chen, Jiayi Chen, Dawei Ge +5
Antiresonant hollow-core fibres (AR-HCFs) have recently reached attenuation far below the Rayleigh-scattering limit of silica, but their inherently multimode nature remains a major…
Co-Propagation of Quantum Time Synchronization and Optical Frequency Transfer over a 122 km Hollow-Core Fiber
Huibo Hong, Xiao Xiang, Runai Quan +15
The co-propagation of quantum and classical signals through shared optical fibers is crucial for scalable quantum networks. However, this coexistence is fundamentally limited by sp…
