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…
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…
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…
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…
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…
