Verification of Bell nonlocality by violating quantum monogamy relations

作者:费少明 研究员(通讯作者)

简介:

Quantum nonlocality as a witness of entanglement plays a crucial
role in various fields. Existing quantum monogamy relations rule
out the possibility of simultaneous violations of any Bell inequalities
with partial statistics generated from one Bell experiment on any
multipartite entanglement or post-quantum source. In this article,
we report an efficient method to construct a multipartite Bell test
based on any Bell inequalities. We demonstrate that violating these
monogamy relations can dynamically witness simultaneous Bell nonlocalities
of partial systems. We conduct a tripartite experiment to
verify quantum nonlocalities by violating a tripartite monogamy
relation using a maximally entangled two-photon state.
