Generalized Mermin Inequalities for Benchmarking Large-Scale GHZ States
Jianbin Cai, Junxiang Huang, Fynn Otto +15
Multipartite Bell tests provide a correlation-only route to benchmarking quantum processors, but their application at large scales is hindered by the rapid decay of many-body corre…
Can outcome communication explain Bell nonlocality?
Carlos Vieira, Carlos de Gois, Pedro Lauand +3
A central aspect of quantum information is that correlations between spacelike separated observers sharing entangled states cannot be reproduced by local hidden variable (LHV) mode…
Qubits in second quantisation in fermionic simulators
Ahana Ghoshal, Carlos de Gois, Kiara Hansenne +2
Simulating many-body fermionic systems in conventional qubit-based quantum computers poses significant challenges due to the overheads associated with the encoding of fermionic sta…
Optimal Overlapping Tomography
Kiara Hansenne, Rui Qu, Lisa T. Weinbrenner +7
Characterising large-scale quantum systems is central to fundamental physics and essential for applications of quantum technologies. While a full characterisation requires exponent…
