Limitations of strong coupling in non-Markovian quantum thermometry
Qing-Shou Tan, Yang Liu, Xulin Liu +3
We investigate quantum thermometry using a single-qubit probe embedded in a non-Markovian environment, employing the numerically exact hierarchical equations of motion (HEOM) to ov…
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…
Generalized Quantum Fluctuation Theorem for Energy Exchange
Wei Wu, Jun-Hong An
The nonequilibrium fluctuation relation is a cornerstone of quantum thermodynamics. It is widely believed that the system-bath heat exchange obeys the famous Jarzynski-Wójcik fluct…
Validating quantum-supremacy experiments with exact and fast tensor network contraction
Yong Liu, Yaojian Chen, Chu Guo +11
The quantum supremacy experiment, such as Google Sycamore [Nature \textbf{574}, 505 (2019)], poses great challenge for classical verification due to the exponentially-increasing co…
