Overcoming the Lamb Shift in System-Bath Interaction Models via KMS Detailed Balance: High-Accuracy Thermalization with Time-Bounded Interactions
Hongrui Chen, Zhiyan Ding, Ruizhe Zhang
We investigate quantum thermal state preparation algorithms based on system-bath interactions and uncover a surprising phenomenon in the weak-coupling regime. We rigorously prove t…

Thermal expectation estimation via single-trajectory Gibbs sampling with non-destructive measurements
Hongrui Chen, Jiaqing Jiang, Bowen Li +1
Estimating thermal expectation values of quantum many-body systems is a central challenge in physics, chemistry, and materials science. Standard quantum Gibbs sampling protocols ad…
