Implementation of the Density-functional Theory on Quantum Computers with Linear Scaling with respect to the Number of Atoms
Taehee Ko, Xiantao Li, Chunhao Wang
Density-functional theory (DFT) has revolutionized computer simulations in chemistry and material science. A faithful implementation of the theory requires self-consistent calculat…
Efficient Quantum Algorithms for Quantum Optimal Control
Xiantao Li, Chunhao Wang
In this paper, we present efficient quantum algorithms that are exponentially faster than classical algorithms for solving the quantum optimal control problem. This problem involve…
Simulating Markovian open quantum systems using higher-order series expansion
Xiantao Li, Chunhao Wang
We present an efficient quantum algorithm for simulating the dynamics of Markovian open quantum systems. The performance of our algorithm is similar to the previous state-of-the-ar…
Quantum Algorithms for Sampling Log-Concave Distributions and Estimating Normalizing Constants
Andrew M. Childs, Tongyang Li, Jin-Peng Liu +2
Given a convex function , the problem of sampling from a distribution is called log-concave sampling. This task has wide app…
Thermal State Preparation via Rounding Promises
Patrick Rall, Chunhao Wang, Pawel Wocjan
A promising avenue for the preparation of Gibbs states on a quantum computer is to simulate the physical thermalization process. The Davies generator describes the dynamics of an o…
On the Quantum Complexity of Closest Pair and Related Problems
Scott Aaronson, Nai-Hui Chia, Han-Hsuan Lin +2
The closest pair problem is a fundamental problem of computational geometry: given a set of points in a -dimensional space, find a pair with the smallest distance. A classic…
