Abstract

A computer-implemented method for determining a quantum phase parameter characterizing a property of a quantum phase of a solid-state material sample, which comprises determining, for a bath site of an impurity-bath model of the solid-state material sample, respective parameters Vp and εp of the bath site, where Vp represents a coupling strength of the bath site, and εp represents an energy of the bath site, configuring a quantum circuit for computing a Green's function of the solid-state material sample corresponding to the impurity-bath model, wherein one or more quantum gates of the quantum circuit are configured based on the determined respective parameters Vp and εp, wherein the quantum circuit is configured to use one or more noisy qubits, wherein respective noise patterns of the noisy qubits are used to represent dissipation of the impurity-bath model; and executing, on a quantum computer, the quantum circuit to determine an estimate of the quantum phase parameter.
