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…
Time-Dependent Hamiltonian Simulation via Time-Independent Dynamics in a Larger Space
Zecheng Li, Chunhao Wang
In this paper, we present a proof-of-concept quantum algorithm for simulating time-dependent Hamiltonian evolution by reducing the problem to simulating a time-independent Hamilton…
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,…
On the (Classical and Quantum) Fine-Grained Complexity of Approximate CVP and Max-Cut
Jeremy Ahrens Huang, Young Kun Ko, Chunhao Wang
We show a linear-size reduction from gap Max-2-Lin(2) (a generalization of the gap - problem) to for and fi…
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…
Stochastic Quantum Sampling for Non-Logconcave Distributions and Estimating Partition Functions
Guneykan Ozgul, Xiantao Li, Mehrdad Mahdavi +1
We present quantum algorithms for sampling from non-logconcave probability distributions in the form of . Here, can be written as a finite sum $f(x):…
