A Quantum Kinetic Monte Carlo Method For Lindblad Equation

Published 8 Jun 2023 in physics.comp-ph | (2306.05102v2)

Abstract: In this paper, we generalize the Quantum Kinetic Monte Carlo (QKMC) method of the Schrodinger equation, which was first proposed by [Z. Cai and J. Lu. SIAM J. Sci. Comput., 40(3):B706-B722, 2018] to the Lindblad equation. This algorithm makes full use of the tensor product structure of the matrices in the Lindblad equation, thus significantly reducing the storage cost, and can calculate a more extensive system than the existing methods. We demonstrate the method in the framework of the dissipative Ising model, and numerical experiments verify the validity of the method and the error analysis.
