Quantum Mpemba Effect Induced by Non-Markovian Exceptional Points
Ze-Zhou Zhang, Hong-Gang Luo, Wei Wu
Quantum Mpemba effect describes an anomalous phenomenon of accelerated relaxation which is of fundamental interest in the field of nonequilibrium thermodynamics. Conventional theor…
Low-temperature Quantum Metrology Enhanced by Strong Couplings
Ze-Zhou Zhang, Hong-Gang Luo, Wei Wu
Equilibrium probes have been widely used in various noisy quantum metrology schemes. However, such an equilibrium-probe-based metrology scenario severely suffers from the low-tempe…
Non-Markovian temperature sensing
Ze-Zhou Zhang, Wei Wu
We investigate the sensing performance of a single-qubit quantum thermometer within a non-Markovian dynamical framework. By employing an exactly numerical hierarchical equations of…
Controllable dynamics of a dissipative two-level system
Wei Wu, Ze-Zhou Zhang
We propose a strategy to modulate the decoherence dynamics of a two-level system, which interacts with a dissipative bosonic environment, by introducing an assisted degree of freed…
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…
Detecting scrambling via statistical correlations between randomized measurements on an NMR quantum simulator
Xinfang Nie, Ze Zhang, Xiuzhu Zhao +3
Out-of-time-order correlator (OTOC), been suggested as a measure of quantum information scrambling in quantum many-body systems, has received enormous attention recently. The exper…
