Probing quantum entanglement from magnetic-sublevels populations: beyond spin squeezing inequalities
Guillem Müller-Rigat, Maciej Lewenstein, Irénée Frérot
Spin squeezing inequalities (SSI) represent a major tool to probe quantum entanglement among a collection of few-level atoms, and are based on collective spin measurements and thei…
Three numerical approaches to find mutually unbiased bases using Bell inequalities
Maria Prat Colomer, Luke Mortimer, Irénée Frérot +2
Mutually unbiased bases correspond to highly useful pairs of measurements in quantum information theory. In the smallest composite dimension, six, it is known that between three an…
Thermal critical dynamics from equilibrium quantum fluctuations
Irénée Frérot, Adam Rançon, Tommaso Roscilde
We show that quantum fluctuations display a singularity at thermal critical points, involving the dynamical exponent. Quantum fluctuations, captured by the quantum variance (I.…
Unveiling quantum entanglement in many-body systems from partial information
Irénée Frérot, Flavio Baccari, Antonio Acín
Quantum entanglement is commonly assumed to be a central resource for quantum computing and quantum simulation. Nonetheless, the capability to detect it in many-body systems is sev…
