Minimal Scenarios Witnessing Genuine Multipartite Nonlocality Possibilistically
Soumyadip Patra, Peter Bierhorst
We study a strong form of genuine multipartite nonlocality (GMNL), where an -partite scenario admits a quantum strategy generating outcomes belonging to a restricted set with ce…
Quantum Advantage over Wirings of Nonsignaling Boxes in Multipartite Networks
Peter Bierhorst, Arkaprabha Ghosal, Soumyadip Patra
Quantum-entangled measurements are known to enable multi-party behaviors that are impossible with unentangled measurements on nonlocal resources, even those that are super-quantum…
Intractability of Witnessing Entangled Measurements Device Independently
Peter Bierhorst
Protocols have been previously proposed to certify the presence of an entangled measurement in a fully device-independent manner. Here, I provide models for these protocols in whic…
Quantitative and Optimal Device-Independent Lower Bounds on Detection Efficiency
Arkaprabha Ghosal, Soumyadip Patra, Peter Bierhorst
This paper examines a quantitative and optimal lower bound on the detector efficiency in a (2,2,2) Bell experiment within a fully device-independent framework, whereby the detector…
No-signalling-projection-invariant Bell inequalities
Soumyadip Patra, Jitendra Prakash, Aaditya Paudel +1
In this paper, we highlight how any Bell inequality for a configuration involving parties each performing one of binary-outcome measurements has a canonical form that is no…
Strength of statistical evidence for genuine tripartite nonlocality
Soumyadip Patra, Peter Bierhorst
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 c…
Consistency and Causality of Interconnected Nonsignaling Resources
Peter Bierhorst
This paper examines networks of measuring parties sharing nonsignaling resources that can be locally wired together: that is, each party follows a scheme to measure the res…
Asymptotically Optimal Adversarial Strategies for the Probability Estimation Framework
Soumyadip Patra, Peter Bierhorst
The Probability Estimation Framework involves direct estimation of the probability of occurrences of outcomes conditioned on measurement settings and side information. It is a powe…
A Hierarchy of Multipartite Nonlocality and Device-Independent Effect Witnesses
Peter Bierhorst, Jitendra Prakash
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-…
Multipartite Intrinsic Non-Locality and Device-Independent Conference Key Agreement
Aby Philip, Eneet Kaur, Peter Bierhorst +1
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 agreemen…
Ruling out Bipartite Nonsignaling Nonlocal Models for Tripartite Correlations
Peter Bierhorst
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…
Scalable multiphoton quantum metrology with neither pre- nor post-selected measurements
Chenglong You, Mingyuan Hong, Peter Bierhorst +8
The quantum statistical fluctuations of the electromagnetic field establish a limit, known as the shot-noise limit, on the sensitivity of optical measurements performed with classi…
Tsirelson Polytopes and Randomness Generation
Peter Bierhorst, Yanbao Zhang
We classify the extreme points of a polytope of probability distributions in the (2,2,2) CHSH-Bell setting that is induced by a single Tsirelson bound. We do the same for a class o…
Certifying Quantum Randomness by Probability Estimation
Yanbao Zhang, Emanuel Knill, Peter Bierhorst
We introduce probability estimation, a broadly applicable framework to certify randomness in a finite sequence of measurement results without assuming that these results are indepe…
Challenging local realism with human choices
The BIG Bell Test Collaboration, C. Abellán, A. Acín +105
A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…
Experimentally Generated Randomness Certified by the Impossibility of Superluminal Signals
Peter Bierhorst, Emanuel Knill, Scott Glancy +9
From dice to modern complex circuits, there have been many attempts to build increasingly better devices to generate random numbers. Today, randomness is fundamental to security an…
Quantum Randomness Generation by Probability Estimation with Classical Side Information
Emanuel Knill, Yanbao Zhang, Peter Bierhorst
We develop a framework for certifying randomness from Bell-test trials based on directly estimating the probability of the measurement outcomes with adaptive test supermartingales.…
Experimentally Generated Random Numbers Certified by the Impossibility of Superluminal Signaling
Peter Bierhorst, Emanuel Knill, Scott Glancy +7
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 numbe…
Chained Bell Inequality Experiment with High-Efficiency Measurements
T. R. Tan, Y. Wan, S. Erickson +6
We report correlation measurements on two Be ions that violate a chained Bell inequality obeyed by any local-realistic theory. The correlations can be modeled as derived fr…
Geometric Decompositions of Bell Polytopes with Practical Applications
Peter Bierhorst
In the well-studied (2,2,2) Bell experiment consisting of two parties, two measurement settings per party, and two possible outcomes per setting, it is known that if the experiment…
A strong loophole-free test of local realism
Lynden K. Shalm, Evan Meyer-Scott, Bradley G. Christensen +31
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 parti…
A Robust Mathematical Model for Clauser-Horne Experiments, With Implications for Rigorous Statistical Analysis
Peter Bierhorst
Recent experiments have reached detection efficiencies sufficient to close the detection loophole, testing the Clauser-Horne (CH) version of Bell's inequality. For a similar future…
A New Loophole in Recent Bell Test Experiments
Peter Bierhorst
Recent experiments have reached detection efficiencies sufficient to close the detection loophole with photons. Both experiments ran multiple successive trials in fixed measurement…
A Rigorous Analysis of the Clauser-Horne-Shimony-Holt Inequality Experiment When Trials Need Not Be Independent
Peter Bierhorst
The Clauser-Horne-Shimony-Holt (CHSH) inequality is a constraint that local theories must obey. Quantum Mechanics predicts a violation of this inequality in certain experimental se…
