Improved Nonlocality Certification via Bouncing between Bell Operators and Inequalities
Weikang Li, Mengyao Hu, Ke Wang +25
Bell nonlocality is an intrinsic feature of quantum mechanics, which can be certified via the violation of Bell inequalities. It is therefore a fundamental question to certify Bell…

Testing the unified bounds of quantum speed limit
Yaozu Wu, Jiale Yuan, Chuanyu Zhang +12
Quantum speed limits (QSLs) impose fundamental constraints on the evolution speed of quantum systems. Traditionally, the Mandelstam-Tamm (MT) and Margolus-Levitin (ML) bounds have…
