Joint IQIM/AWS Seminar Series

Quantum thermal state preparation
Chi-Fang (Anthony) Chen, Brandao Group,

Abstract: A key subroutine in quantum computing is to prepare thermal states or ground states of Hamiltonians, with applications in simulating properties of quantum systems. Today, I will talk about a family of quantum algorithms for this task. Physically, our algorithms distill the essence of system-bath interaction by simulating an effective Lindbladian; computationally, our algorithms are quantum analogs of classical Markov chain Monte Carlo sampling. Given the ubiquity of thermodynamics and the triumph of classical Monte Carlo methods, we anticipate that quantum thermal state preparation will become indispensable in quantum computing.

Joint work with Michael J. Kastoryano, Fernando G.S.L. Brandão, and András Gilyén. https://arxiv.org/abs/2303.18224

***Please note a change in location. The May 3 Seminar will be held in B157, the Basement Conference Room in West Bridge.

Lunch will be provided, following the talk, on the lawn north of the Bridge Arcade
