DOI: 10.1088/1367-2630/ad48af
Abstract: In the standard Bell experiment, two parties perform local projective measurements on a shared pair of entangled qubits to generate nonlocal correlations. However, these measurements completely destroy the entanglement, rendering the post-measurement state unable for… read more here.
