Verifying Multipartite Entangled GHZ States via Multiple Quantum Coherences
Ken X. Wei, Isaac Lauer, Srikanth Srinivasan +6
The ability to generate and verify multipartite entanglement is an important benchmark for near-term quantum devices devices. We develop a scalable entanglement metric based on mul…
Emergent perturbation independent decay of the Loschmidt echo in a many-spin system studied through scaled dipolar dynamics
Claudia M. Sánchez, Ana Karina Chattah, Ken Xuan Wei +3
Evaluating the role of perturbations versus the intrinsic coherent dynamics in driving to equilibrium is of fundamental interest to understand quantum many-body thermalization, in…
Comparing many-body localization lengths via non-perturbative construction of local integrals of motion
Pai Peng, Zeyang Li, Haoxiong Yan +2
Many-body localization (MBL), characterized by the absence of thermalization and the violation of conventional thermodynamics, has elicited much interest both as a fundamental phys…
Emergent prethermalization signatures in out-of-time ordered correlations
Ken Xuan Wei, Pai Peng, Oles Shtanko +4
How a many-body quantum system thermalizes --or fails to do so-- under its own interaction is a fundamental yet elusive concept. Here we demonstrate nuclear magnetic resonance obse…
