Complementary to tensor network methods, quantum Monte Carlo is suited for 2D systems at high temperatures; we have applied the determinant quantum Monte Carlo (DQMC) algorithm to a three-band Hubbard model of high-Tc cuprate superconductors. Selected publications and preprints: Irene López-Gutiérrez, Christian B. Mendl With a quantum computer of that size, it is possible scientists will be able to build a circuit with enough gates to solve the Fermi-Hubbard model using the algorithm Phasecraft demonstrated. We take the following approach to solve the Hubbard model (or related models) on a quantum computer: 1.

Sampling the is the easiest task for Our work studied the Fermi-Hubbard model, which is a famous unsolved problem in many-body physics, despite its simple structure and relevance to fields such as high-temperature superconductivity. The idea behind the VQE algorithm is to optimise over a family of quantum circuits - an "ansatz" - for producing the ground state of a quantum system.

The efficient simulation of correlated quantum systems is a promising near-term application of quantum computers. Here, we present a measurement of the second R\\'enyi entropy of the ground state of the two-site Fermi-Hubbard model on a five-qubit programmable quantum computer based on trapped ions. Our work illustrates the extraction of a nonlinear characteristic of a quantum state using a

In quantum many-body systems like the Hubbard model and related models considered here, even this basic task can be anything but trivial as the dimensionality of the Hilbert space d H, typically grows exponentially with the number of interacting particles. While the evolution of a quantum state under a Hamiltonian is straightforward (if sometimes expensive), using quantum computers to determine the ground state phase diagram of a quantum model and the properties of its phases is more involved. Using the Hubbard model as a prototypical example, we here show all the steps necessary to determine its phase diagram and ground state properties on a quantum computer. Using the Hubbard model as a prototypical example, we here show all the steps necessary to determine its phase diagram and ground-state properties on a quantum computer. In particular, we discuss strategies for efficiently determining and preparing the ground state of the Hubbard model starting from various mean-field states with broken symmetry. In the cases of the transverse field Ising and the Bose-Hubbard models in 1d, it was demonstrated that certain characteristics of the mutual information network can be used to detect quantum phase These concepts are then applied by implementing the 2D Hubbard model for fermions interacting on a lattice.
