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…
Infinite-dimensional Extension of the Linear Combination of Hamiltonian Simulation: Theorems and Applications
Rundi Lu, Hao-En Li, Zhengwei Liu +1
We generalize the Linear Combination of Hamiltonian Simulation (LCHS) formula [An, Liu, Lin, Phys. Rev. Lett. 2023] to simulate time-evolution operators in infinite-dimensional spa…
Towards robust variational quantum simulation of Lindblad dynamics via stochastic Magnus expansion
Jia-Cheng Huang, Hao-En Li, Yi-Cheng Wang +3
In this paper, we introduce a novel and general framework for the variational quantum simulation of Lindblad equations. Building on the close relationship between the unraveled Lin…
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…
