Efficient heralding of O-band passively spatial-multiplexed photons for noise-tolerant quantum key distribution
Mao Tong Liu, Han Chuen Lim
When implementing O-band quantum key distribution on optical fiber transmission lines carrying C-band data traffic, noise photons that arise from spontaneous Raman scattering or in…
Transmission of O-band wavelength-division-multiplexed heralded photons over a noise-corrupted optical fiber channel
Mao Tong Liu, Han Chuen Lim
We transmitted O-band heralded photons over 10 km of optical fiber in a proof-of-concept experiment demonstrating the feasibility of using heralded photons to improve the noise tol…
Wavelength-Multiplexed Entanglement Distribution over 10 km of Fiber
Han Chuen Lim, Akio Yoshizawa, Hidemi Tsuchida +1
We report the first experimental demonstration of wavelength-multiplexed entanglement distribution. 44 channels of highly-entangled photon-pairs from one single broadband source ar…
All-Fiber Source of Polarization-Entangled Photon Pairs Based on a Novel Birefringence Compensated Scheme
Han Chuen Lim, Dexiang Wang, Takuo Tanemura +2
We propose a new all-fiber source of polarization-entangled photon pairs for quantum communications. Fiber birefringence is compensated using Faraday rotator mirror, resulting in e…
