Fibre polarization state compensation in entanglement-based quantum key distribution
Yicheng Shi, Hou Shun Poh, Alexander Ling +1
Quantum Key Distribution (QKD) using polarisation encoding can be hard to implement over deployed telecom fibres because the routing geometry and the birefringence of the fibre lin…
Stable Polarization Entanglement based Quantum Key Distribution over Metropolitan Fibre Network
Yicheng Shi, Soe Moe Thar, Hou Shun Poh +3
We demonstrate a quantum key distribution implementation over deployed dark telecom fibers with polarisation-entangled photons generated at the O-band. One of the photons in the pa…
Characterizing nonlocal dispersion compensation in deployed telecommunications fiber
James A. Grieve, Yicheng Shi, Hou Shun Poh +2
Propagation of broadband photon pairs over deployed telecommunication fibers is used to achieve nonlocal dispersion compensation without the deliberate introduction of negative dis…
Breakdown flash at telecom wavelengths in InGaAs avalanche photodiodes
Yicheng Shi, Janet Zheng Jie Lim, Hou Shun Poh +4
Quantum key distribution (QKD) at telecom wavelengths (1260-1625nm) has the potential for fast deployment due to existing optical fibre infrastructure and mature telecom technologi…
Random numbers from vacuum fluctuations
Yicheng Shi, Brenda Chng, Christian Kurtsiefer
We implement a quantum random number generator based on a balanced homodyne measurement of vacuum fluctuations of the electromagnetic field. The digitized signal is directly proces…
