A Generalized Landauer's Principle for Unitarily Transformed Thermal Reservoirs
Hao Xu
Landauer's principle, a cornerstone of quantum information and thermodynamics, appears to be violated when the thermal reservoir is replaced by a squeezed thermal state (STS), owin…

Measurement-Induced Perturbations of Hausdorff Dimension in Quantum Paths
You-Wei Ding, Yen Chin Ong, Hao Xu
In a seminal paper, Abbott et al. analyzed the relationship between a particle's trajectory and the resolution of position measurements performed by an observer at fixed time inter…

Distinguishing pure and thermal states by Landauer's principle in open systems
Hao Xu
Starting from Polchinski's thought experiment on how to distinguish between pure and thermal states, we construct a specific system to study the interaction between qubit and cavit…
