Inferring Nonlinear Many-Body Bell Inequalities From Average Two-Body Correlations: Systematic Approach for Arbitrary Spin-j Ensembles
Guillem Müller-Rigat, Albert Aloy, Maciej Lewenstein +1
Violating Bell's inequalities (BIs) allows one to certify the preparation of entangled states from minimal assumptions -- in a device-independent manner. Finding BIs tailored to ma…
Detecting many-body Bell non-locality by solving Ising models
Irénée Frérot, Tommaso Roscilde
Bell non-locality represents the ultimate consequence of quantum entanglement, fundamentally undermining the classical tenet that spatially-separated degrees of freedom possess obj…
Bell correlations at Ising quantum critical points
Angelo Piga, Albert Aloy, Maciej Lewenstein +1
When a collection of distant observers share an entangled quantum state, the statistical correlations among their measurements may violate a many-body Bell inequality, demonstratin…
Reconstructing the quantum critical fan of strongly correlated systems via quantum correlations
Irénée Frérot, Tommaso Roscilde
Albeit occurring at zero temperature, quantum critical phenomena are known to have a huge impact on the finite-temperature phase diagram of strongly correlated systems -- an aspect…
