A universal setup for active control of a single-photon detector
Qin Liu, Antía Lamas-Linares, Christian Kurtsiefer +3
The influence of bright light on a single-photon detector has been described in a number of recent publications. The impact on quantum key distribution (QKD) is important, and seve…

Experimentally faking the violation of Bell's inequalities
Ilja Gerhardt, Qin Liu, Antía Lamas-Linares +4
Entanglement witnesses such as Bell inequalities are frequently used to prove the non-classicality of a light source and its suitability for further tasks. By demonstrating Bell in…

Full-field implementation of a perfect eavesdropper on a quantum cryptography system
Ilja Gerhardt, Qin Liu, Antia Lamas-Linares +3
Quantum key distribution (QKD) allows two remote parties to grow a shared secret key. Its security is founded on the principles of quantum mechanics, but in reality it significantl…
