This work proposes a framework for DMFT calculations on quantum computers, focusing on near-term applications. It leverages the structure of the impurity problem, combining a low-rank Gaussian subspace representation of the ground state and a compressed, short-depth quantum circuit that joins the Gaussian state preparation with the time evolution to compute the necessary Green's functions.
HamLib is an extensive dataset of qubit Hamiltonians spanning a large range of problem sizes and instances that is designed for testing quantum algorithms, software and hardware.
In this paper, we introduce the multi-observable dynamic mode decomposition (MODMD) approach combining ODMD with classical shadows for efficient low-lying energy computations on near-term and early fault-tolerant quantum computers.
