Quantum Markov State Models for Metastable Dynamics
Hao-En Li, Lin Lin, Michael Ragone
Open quantum systems can rapidly lose most microscopic information, leaving only a few degrees of freedom to govern their long-time dynamics. Classical Markov state models (MSMs) d…
Dissipative phase decision without ground-state preparation
Hao-En Li, Yilun Yang, Lin Lin
We propose a dynamical approach to identifying ground-state quantum phases through short-time dissipative cooling. Rather than determining the phase by preparing highly accurate ap…
Quantum Estimation of Non-Hermitian Pseudospectra
Gengzhi Yang, Jiaqi Leng, Xiaodi Wu +1
Non-Hermitian many-body systems can be spectrally unstable, so small perturbations may induce large eigenvalue shifts. The pseudospectrum quantifies this instability and provides a…
Dissipative quantum algorithms for excited-state quantum chemistry
Hao-En Li, Lin Lin
Electronic excited states are central to a vast array of physical and chemical phenomena, yet accurate and efficient methods for preparing them on quantum devices remain challengin…
Simple and efficient end-to-end quantum thermal and ground state preparation
Zhiyan Ding, Yongtao Zhan, John Preskill +1
Quantum computing algorithms for many-body physics, chemistry and materials science typically require the preparation of thermal or ground states for a given Hamiltonian. We propos…
Rapid quantum ground state preparation via dissipative dynamics
Yongtao Zhan, Zhiyan Ding, Jakob Huhn +4
Inspired by natural cooling processes, dissipation has become a promising approach for preparing low-energy states of quantum systems. However, the potential of dissipative protoco…
Dissipative ground state preparation in ab initio electronic structure theory
Hao-En Li, Yongtao Zhan, Lin Lin
Dissipative engineering is a powerful tool for quantum state preparation, and has drawn significant attention in quantum algorithms and quantum many-body physics in recent years. I…
