Temperature insensitive type II quasi-phasematched spontaneous parametric downconversion
Xin-Yi Pan, Christian Kurtsiefer, Alexander Ling +1
The temperature dependence of the refractive indices of potassium titanyl phosphate (KTP) are shown to enable quasi-phasematched type II spontaneous parametric downconversion (SPDC…
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…
Satellite quantum communications when man-in-the-middle attacks are excluded
Tom Vergoossen, Robert Bedington, James A Grieve +1
An application of quantum communications is the transmission of qubits to create shared symmetric encryption keys in a process called Quantum Key Distribution (QKD). Contrary to pu…
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…
Mapping a quantum walk by tuning the coupling coefficient
Kian Fong Ng, Manuel J. L. F. Rodrigues, José Viana-Gomes +2
We present a method to map the evolution of photonic random walks that is compatible with nonclassical input light. Our approach leverages a newly developed flexible waveguide plat…
Extreme environmental testing of a rugged correlated photon source
James A. Grieve, Robert Bedington, Alexander Ling
Experiments in long distance quantum key distribution have motivated the development of ruggedised single photon sources, capable of producing useful correlations even when removed…
