Practical Quantum Sensing with Thermal Light
Peng Kian Tan, Xi Jie Yeo, Alvin Zhen Wei Leow +2
Many quantum sensing suggestions rely on temporal correlations found in photon pairs generated by parametric down-conversion. In this work, we show that the temporal correlations i…
Countering detector manipulation attacks in quantum communication through detector self-testing
Lijiong Shen, Christian Kurtsiefer
In practical quantum key distribution systems, imperfect physical devices open security loopholes that challenge the core promise of this technology. Apart from various side channe…
Distributing Polarization Entangled Photon Pairs with High Rate over Long Distance through Standard Telecommunication Fiber
Lijiong Shen, Chang Hoong Chow, Justin Yu Xiang Peh +3
Entanglement distribution over long distances is essential for many quantum communication schemes like quantum teleportation, some variants of quantum key distribution, or implemen…
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…
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…
Absolute clock synchronization with a single time-correlated photon pair source over 10km
Jianwei Lee, Lijiong Shen, Adrian Nugraha Utama +1
We demonstrate a point-to-point clock synchronization protocol based on bidirectionally propagating photons generated in a single spontaneous parametric down-conversion (SPDC) sour…
