Optimal entanglement witnesses: a scalable data-driven approach

no code implementations • 6 Jan 2021 • Irénée Frérot, Tommaso Roscilde

Multipartite entanglement is the key resource allowing quantum devices to outperform their classical counterparts, and entanglement certification is fundamental to assess any quantum advantage.

Inferring Nonlinear Many-Body Bell Inequalities From Average Two-Body Correlations: Systematic Approach for Arbitrary Spin-j Ensembles

1 code implementation • 15 Dec 2020 • Guillem Müller-Rigat, Albert Aloy, Maciej Lewenstein, Irénée Frérot

This very flexible method, whose complexity does not scale with the system size, allows us to systematically improve over all previously-known Bell's inequalities robustly violated by ensembles of quantum spin-$1/2$; and to discover novel families of Bell's inequalities, tailored to spin-squeezed states and many-body spin singlets of arbitrary spin-$j$ ensembles.
