Exploring the landscape of compact magic-state distillation factories
Hugo Jacinto, Xavier Valcarce, Victor Barizien +2
Producing high-fidelity magic states using the smallest possible number of physical qubits and operations stands as a very important challenge to achieve fault-tolerant quantum com…
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…
Automated generation of photonic circuits for Bell tests with homodyne measurements
Corentin Lanore, Federico Grasselli, Xavier Valcarce +2
Nonlocal quantum realizations, certified by the violation of a Bell inequality, are core resources for device-independent quantum information processing. Although proof-of-principl…
Long-distance device-independent quantum key distribution using single-photon entanglement
Anna Steffinlongo, Mariana Navarro, Marina Cenni +3
Device-independent quantum key distribution (DIQKD) provides the strongest form of quantum security, as it allows two honest users to establish secure communication channels even w…
Complete Self-Testing of a System of Remote Superconducting Qubits
Simon Storz, Anatoly Kulikov, Josua D. Schär +6
Self-testing protocols enable the certification of quantum systems in a device-independent manner, i.e. without knowledge of the inner workings of the quantum devices under test. H…
Realistic Bell tests with homodyne measurements
Enky Oudot, Gaël Massé, Xavier Valcarce +1
We analyze Bell inequalities violations in photonic experiments for which the measurement apparatuses are restricted to homodyne measurements. Through numerical optimization of the…
Automated design of quantum optical experiments for device-independent quantum key distribution
Xavier Valcarce, Pavel Sekatski, Elie Gouzien +2
Device-independent quantum key distribution (DIQKD) reduces the vulnerability to side-channel attacks of standard QKD protocols by removing the need for characterized quantum devic…
Self-testing two-qubit maximally entangled states from generalized CHSH tests
Xavier Valcarce, Julian Zivy, Nicolas Sangouard +1
Device-independent certification, also known as self-testing, aims at guaranteeing the proper functioning of untrusted and uncharacterized devices. For example, the quality of an u…
Device-independent quantum key distribution from generalized CHSH inequalities
P. Sekatski, J. -D. Bancal, X. Valcarce +3
Device-independent quantum key distribution aims at providing security guarantees even when using largely uncharacterised devices. In the simplest scenario, these guarantees are de…
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…
