Experimental Observation of Equilibrium and Dynamical Quantum Phase Transitions via Out-of-Time-Ordered Correlators
Xinfang Nie, Bo-Bo Wei, Xi Chen +8
The out-of-time-ordered correlators (OTOC) have been established as a fundamental concept for quantifying quantum information scrambling and diagnosing quantum chaotic behavior. Re…
Device-independent randomness expansion against quantum side information
Wen-Zhao Liu, Ming-Han Li, Sammy Ragy +9
The ability to produce random numbers that are unknown to any outside party is crucial for many applications. Device-independent randomness generation does not require trusted devi…
Quantum Control via Stimulated Raman User-defined Passage
Jingjing Niu, Bao-Jie Liu, Yuxuan Zhou +9
Stimulated Raman adiabatic passage (STIRAP) is a widely-used technique of coherent state-to-state manipulation for many applications in physics, chemistry, and beyond. The adiabati…
Unified Approach to Witness Nonentanglement-Breaking Quantum Channels
