• Authors: Yan-Han Yang, Xin-Zhu Liu, Xing-Zhou Zheng, Shao-Ming Fei, Ming-Xing Luo,
• Abstract summary: Existing quantum monogamy relations rule out the possibility of simultaneous violations of 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.

• Abstract: 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 sources. In this paper, we report an efficient method to construct 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.

• Probing many-body Bell correlation depth with superconducting qubits [17.3215930037341]
  We report an experimental certification of genuine multipartite Bell correlations, which signal nonlocality in quantum many-body systems. In particular, we employ energy as a Bell correlation witness and variationally decrease the energy of a many-body system across a hierarchy of thresholds. Our results establish a viable approach for preparing and certifying multipartite Bell correlations, which provide a finer benchmark beyond entanglement for quantum devices.

• Unmasking the Polygamous Nature of Quantum Nonlocality [0.4523163728236145]
  Quantum mechanics imposes limits on the statistics of certain observables. In the simplest case of three observers, it has been shown that if two observers violate a Bell inequality then none of them can violate any Bell inequality with the third observer. Here we show that the Bell monogamy does not hold universally and that in fact the only monogamous situation exists for only three observers.

• Bell inequality violations with random mutually unbiased bases [0.0]
  We investigate the problem of exhibiting Bell nonlocality for a two-qudit entangled pure state using a randomly chosen set of mutually unbiased bases. We find that even if we employ only two-setting Bell inequalities, we find a significant chance of obtaining a Bell violation if the two parties are individually allowed to measure a sufficient number of MUBs.

  This work presents a simple and broadly applicable self-testing argument for N-partite correlation Bell inequalities with two binary outcome observables per party. To showcase the versatility of our proof technique, we obtain self-testing statements for N party Mermin-Ardehali-Bei-Klyshko (MABK) and Werner-Wolf-Weinfurter-.Zukowski-Brukner (WWW.ZB) family of linear Bell inequalities.

  We experimentally observe the violations of Leggett-Garg-Bell's inequalities on single and multi-qubit systems. Our analysis highlights the limits of nowadays quantum platforms, showing that the above-mentioned correlation functions deviate from theoretical prediction as the number of qubits and the depth of the circuit grow.

  We show that the nonlocality of single-photon entangled states can nevertheless be revealed in a quantum network made only of beamsplitters and photodetectors. Our results show that single-photon entanglement may constitute a promising solution to generate genuine network-nonlocal correlations useful for Bell-based quantum information protocols.

• Constructing Multipartite Bell inequalities from stabilizers [21.98685929768227]
  We propose a systematical framework to construct Bell inequalities from stabilizers maximally violated by general stabilizer states. We show that the constructed Bell inequalities can self-test any stabilizer state which is essentially device-independent. Our framework can not only inspire more fruitful multipartite Bell inequalities from conventional verification methods, but also pave the way for their practical applications.
