Quantum Regression Theory and Efficient Computation of Response Functions for Non-Markovian Open Systems
Xiantao Li, Chunhao Wang
Linear response functions are a cornerstone concept in physics as they enable efficient estimation of many dynamical properties. In addition to predicting dynamics of observables u…
Quantum Speedups for Sampling and Non-convex Optimization with Stochastic Oracles
Guneykan Ozgul, Xiantao Li, Mehrdad Mahdavi +1
We present quantum speedups for sampling from distributions of the form on . We consider two stochastic oracle models: a stochastic gradient oracle,…
Toward end-to-end quantum simulation for protein dynamics
Zhenning Liu, Xiantao Li, Chunhao Wang +1
Modeling and simulating the protein folding process overall remains a grand challenge in computational biology. We systematically investigate end-to-end quantum algorithms for simu…
Efficient Optimal Control of Open Quantum Systems
Wenhao He, Tongyang Li, Xiantao Li +3
The optimal control problem for open quantum systems can be formulated as a time-dependent Lindbladian that is parameterized by a number of time-dependent control variables. Given…
