Quasi-Lindblad pseudomode theory for open quantum systems

G Park, Z Huang, Y Zhu, C Yang, GKL Chan, L Lin - Physical Review B, 2024 - APS
We introduce a new framework to study the dynamics of open quantum systems with linearly
coupled Gaussian baths. Our approach replaces the continuous bath with an auxiliary …

Quantum phase estimation by compressed sensing

C Yi, C Zhou, J Takahashi - Quantum, 2024 - quantum-journal.org
As a signal recovery algorithm, compressed sensing is particularly effective when the data
has low complexity and samples are scarce, which aligns natually with the task of quantum …

A perturbative analysis for noisy spectral estimation

L Ying - Applied and Computational Harmonic Analysis, 2025 - Elsevier
Spectral estimation is a fundamental task in signal processing. Recent algorithms in
quantum phase estimation are concerned with the large noise, large frequency regime of the …
