Strength of statistical evidence for genuine tripartite nonlocality Open
Recent advancements in network nonlocality have led to the concept of local operations and shared randomness-based genuine multipartite nonlocality (LOSR-GMNL). In this paper, we consider two recent experimental demonstrations of LOSR-GMNL…

Consistency and Causality of Interconnected Nonsignaling Resources Open
This paper examines networks of $n$ measuring parties sharing $m$ nonsignaling resources that can be locally wired together: that is, each party follows a scheme to measure the resources in a cascaded fashion with inputs to later resources…

Asymptotically Optimal Adversarial Strategies for the Probability Estimation Framework Open
The probability estimation framework involves direct estimation of the probability of occurrences of outcomes conditioned on measurement settings and side information. It is a powerful tool for certifying randomness in quantum nonlocality …

A Hierarchy of Multipartite Nonlocality and Device-Independent Effect Witnesses Open
According to recent new definitions, a multi-party behavior is genuinely multipartite nonlocal (GMNL) if it cannot be modeled by measurements on an underlying network of bipartite-only nonlocal resources, possibly supplemented with local (…

Multipartite Intrinsic Non-Locality and Device-Independent Conference Key Agreement Open
In this work, we introduce multipartite intrinsic non-locality as a method for quantifying resources in the multipartite scenario of device-independent (DI) conference key agreement. We prove that multipartite intrinsic non-locality is add…

Intrinsic Non-Locality and Device-Independent Conference Key Agreement. Open
In this work, we introduce the multipartite intrinsic non-locality as a resource quantifier for the multipartite scenario of device-independent (DI) conference key agreement. We prove that this quantity is additive, convex, and monotone un…

Scalable multiphoton quantum metrology with neither pre- nor post-selected measurements Open
The quantum statistical fluctuations of electromagnetic fields establish a limit, known as the shot-noise limit, on the sensitivity of optical measurements performed with classical technologies. However, quantum technologies are not constr…

Ruling out bipartite nonsignaling nonlocal models for tripartite correlations Open
Many three-party correlations, including some that are commonly described as genuinely tripartite nonlocal, can be simulated by a network of underlying subsystems that display only bipartite nonsignaling nonlocal behavior. Quantum mechanic…

Certifying quantum randomness by probability estimation Open
We introduce probability estimation, a broadly applicable framework to certify randomness in a finite sequence of measurement results without assuming that these results are independent and identically distributed. Probability estimation c…

Chained Bell Inequality Experiment with High-Efficiency Measurements Open
We report correlation measurements on two ^{9}Be^{+} ions that violate a chained Bell inequality obeyed by any local-realistic theory. The correlations can be modeled as derived from a mixture of a local-realistic probabilistic distributio…

Experimentally Generated Random Numbers Certified by the Impossibility of Superluminal Signaling Open
Random numbers are an important resource for applications such as numerical simulation and secure communication. However, it is difficult to certify whether a physical random number generator is truly unpredictable. Here, we exploit the ph…

Strong Loophole-Free Test of Local Realism Open
We present a loophole-free violation of local realism using entangled photon pairs. We ensure that all relevant events in our Bell test are spacelike separated by placing the parties far enough apart and by using fast random number generat…

A robust mathematical model for a loophole-free Clauser–Horne experiment Open
Recent experiments have reached detection efficiencies sufficient to close\nthe detection loophole, testing the Clauser-Horne (CH) version of Bell's\ninequality. For a similar future experiment to be completely loophole-free, it\nwill be i…
