Paradox-free classical non-causality and unambiguous non-locality without entanglement are equivalent
Hippolyte Dourdent, Kyrylo Simonov, Andreas Leitherer +5
Closed timelike curves (CTCs) challenge our conception of causality by allowing information to loop back into its own past. Any consistent description of such scenarios must avoid…
Certifying Majorana Fermions with Elegant-Like Bell Inequalities and a New Self-Testing Equivalence
Patryk Michalski, Arturo Konderak, Wojciech Bruzda +1
Bell inequalities provide a fundamental tool for probing nonlocal correlations, yet their quantum bound, that is, the maximal value attainable through quantum strategies, is rarely…
Equivalence of Genuine Multipartite Entanglement and Nonlocality of Nearly Symmetric Multiqubit Pure States
Jakub Wójcik, Wojciech Bruzda, Ignacy Stachura +1
Whether every pure genuinely multipartite entangled (GME) state necessarily exhibits genuine multipartite nonlocality (GMNL) remains an open question. By combining a recently propo…
Robust Self-Testing of Multiqudit Supersinglet Slater States via Constant Number of Binary Measurements
Arturo Konderak, Wojciech Bruzda, Remigiusz Augusiak
Self-testing is a powerful device-independent technique that enables one to deduce the forms of both the quantum state and the measurements involved in a physical experiment based…
Entanglement witnesses for stabilizer states and subspaces beyond qubits
Jakub Szczepaniak, Owidiusz Makuta, Remigiusz Augusiak
Genuine multipartite entanglement is arguably the most valuable form of entanglement in the multipartite case, with applications, for instance, in quantum metrology. In order to de…
Local unambiguous unidentifiability, entanglement generation, and Hilbert space splitting
Saronath Halder, Remigiusz Augusiak
We consider collections of mixed states supported on mutually orthogonal subspaces whose rank add up to the total dimension of the underlying Hilbert space. We then ask whether it…
