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…
Quantum Position Verification with Remote Untrusted Devices
Gautam A. Kavuri, Yanbao Zhang, Abigail R. Gookin +16
Position information underpins many modern technologies, from navigation and timing to authentication and critical infrastructure. However, classical methods of proving that inform…
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…
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…
