Asymptotic Entanglement Hiding under Stabilizer Restrictions
Jicun Li, Wei Xie, Jun Wu +2
Entanglement is central to quantum information processing, while stabilizer operations underpin fault-tolerant quantum computation. We ask how much entanglement remains visible or…
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…
