Family of Bell-like inequalities as device-independent witnesses for entanglement depth
Yeong-Cherng Liang, Denis Rosset, Jean-Daniel Bancal +3
We present a simple family of Bell inequalities applicable to a scenario involving arbitrarily many parties, each of which performs two binary-outcome measurements. We show that th…
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…
Robust self testing of the 3-qubit state
Xingyao Wu, Yu Cai, Tzyh Haur Yang +3
Self-testing is a device independent method which can be used to determine the nature of a physical system or device, without knowing any detail of the inner mechanism or the physi…
More randomness from noisy sources
Jean-Daniel Bancal, Valerio Scarani
Bell experiments can be used to generate private random numbers. An ideal Bell experiment would involve measuring a state of two maximally entangled qubits, but in practice any sta…
Robust and versatile black-box certification of quantum devices
Tzyh Haur Yang, Tamás Vértesi, Jean-Daniel Bancal +2
Self-testing refers to the fact that, in some quantum devices, both states and measurements can be assessed in a black-box scenario, on the sole basis of the observed statistics, i…
Witnessing single-photon entanglement with local homodyne measurements: analytical bounds and robustness to losses
Melvyn Ho, Olivier Morin, Jean-Daniel Bancal +3
Single-photon entanglement is one of the primary resources for quantum networks, including quantum repeater architectures. Such entanglement can be revealed with only local homodyn…
