Loss-tolerant quantum secure positioning with weak laser sources
Charles Ci Wen Lim, Feihu Xu, George Siopsis +3
Quantum position verification (QPV) is the art of verifying the geographical location of an untrusted party. Recently, it has been shown that the widely studied Bennett & Brassard…
Detector-Device-Independent Quantum Key Distribution
Charles Ci Wen Lim, Boris Korzh, Anthony Martin +3
Recently, a quantum key distribution (QKD) scheme based on entanglement swapping, called measurement-device-independent QKD (mdiQKD), was proposed to bypass all detector side-chann…
Comparing different approaches for generating random numbers device-independently using a photon pair source
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +6
What is the most efficient way to generate random numbers device-independently using a photon pair source based on spontaneous parametric down conversion (SPDC)? We consider this q…
Random Variation of Detector Efficiency: A Countermeasure against Detector Blinding Attacks for Quantum Key Distribution
Charles Ci Wen Lim, Nino Walenta, Matthieu Legre +2
In the recent decade, it has been discovered that QKD systems are extremely vulnerable to side-channel attacks. In particular, by exploiting the internal working knowledge of pract…
Provably Secure and Practical Quantum Key Distribution over 307 km of Optical Fibre
Boris Korzh, Charles Ci Wen Lim, Raphael Houlmann +6
Proposed in 1984, quantum key distribution (QKD) allows two users to exchange provably secure keys via a potentially insecure quantum channel. Since then, QKD has attracted much at…
Challenging preconceptions about Bell tests with photon pairs
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +7
Motivated by very recent experiments, we consider a scenario "à la Bell" in which two protagonists test the Clauser-Horne-Shimony-Holt (CHSH) inequality using a photon-pair source…
