Heralded distribution of single-photon path entanglement
Patrik Caspar, Ephanielle Verbanis, Enky Oudot +9
We report the experimental realization of heralded distribution of single-photon path entanglement at telecommunication wavelengths in a repeater-like architecture. The entanglemen…
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…
Bipartite nonlocality with a many-body system
Enky Oudot, Jean-Daniel Bancal, Pavel Sekatski +1
We consider a bipartite scenario where two parties hold ensembles of -spins which can only be measured collectively. We give numerical arguments supporting the conjecture that…
Witnessing Opto-Mechanical Entanglement with Photon-Counting
Melvyn Ho, Enky Oudot, Jean-Daniel Bancal +1
The ability to coherently control mechanical systems with optical fields has made great strides over the past decade, and now includes the use of photon counting techniques to dete…
