Towards Device-Independent Quantum Key Distribution with Photonic Devices
Corentin Lanore, Xavier Valcarce, Jean Etesse +2
Quantum Key Distribution (QKD) protocols enable two distant parties to communicate with information-theoretically proven secrecy. However, these protocols are generally vulnerable…

Unitary Synthesis with AlphaZero via Dynamic Circuits
Xavier Valcarce, Bastien Grivet, Nicolas Sangouard
Unitary synthesis is the process of decomposing a target unitary transformation into a sequence of quantum gates. This is a challenging task, as the number of possible gate combina…

What is the minimum CHSH score certifying that a state resembles the singlet?
Xavier Valcarce, Pavel Sekatski, Davide Orsucci +3
A quantum state can be characterized from the violation of a Bell inequality. The well-known CHSH inequality for example can be used to quantify the fidelity (up to local isometrie…
