We test the performance of the VHA when applied to the Hubbard model in the presence of unitary control errors on quantum computers with realistic gate fidelities. A key goal of digital quantum computing is the simulation of fermionic systems such as molecules or the Hubbard model.

Technol. 4, 035005 (2019 ) Dec 12, 2019 state of the Hubbard model using variational methods has been predicted to be one of the first applications of near-term quantum computers. Finding the ground state of the Hubbard model using variational methods has been predicted to be one of the first applications of near-term quantum computers .

Before we decide to use a quantum computer to figure out some properties of the Hubbard model, let’s try to make some progress with paper-and-pencil. Some materials that were predicted to conduct electricity turned out to be insulators, especially at low temperatures. Simulation of spin and charge dynamics in the Fermi-Hubbard model. This module contains an implementation of code to simulate the dynamics of the one-dimensional Fermi-Hubbard model on Google's Quantum Computing Service. The Bose-Hubbard Model is QMA-complete Andrew M. ChildsDavid GossetZak Webb Received July 31, 2014; Revised June 25, 2015; Published December 31, 2015 Abstract: The Bose-Hubbard model is a system of interacting bosons that live on the vertices of a graph. The particles can move between adjacent vertices and experience a repulsive on-site interaction. for each vertex occupied by more than one particle.

In the 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. 2018-11-11 2020-12-10 2015-12-10 2019-12-12 2021-03-25 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 Our graph is only for a single siteHubbard model. Having to account for tunneling terms and more sites would make finding the eigenvalues/vectors (and thus calculating \(\rho\)) much harder. This is the first problem we’ll try solving with a quantum computer.

For the Hubbard model in the 2D square lattice, the charge gap opens starting from an inﬁnitesimal U.The low-energy physics is described by the AF Heisenberg model. For the SU(2) case, quantum spin ﬂuctuations are not strong Hubbard model can be simulated on a quantum computer and can simulate arbitrary quantum computations, the complexity of simulating the model is therefore precisely the power of quantum computation. In our work, we prove an analogous result for the Fermi-Hubbard model – a broadly applicable model with relevance to 2015-09-17 · In this article, we have shown that that rich variety of behavior extends to universal quantum computation: simulating the Hubbard model on an arbitrary graph, both just below half-filling and in the dilute limit, is as hard as simulating arbitrary quantum computers. The graph itself encodes the computation to be performed. Finding the ground state of the Fermi-Hubbard model has been predicted to be one of the first applications of near-term quantum computers and one that offers a pathway to understanding and Finding the ground state of the Fermi-Hubbard model has been predicted to be one of the first applications of near-term quantum computers, and one that offers a pathway to understanding and Titel Quantum Compactons in an extended Bose-Hubbard Model Title Kvantkompaktoner i en utvidgad Bose-Hubbard model Författare Peter Jason Author Sammanfattning Abstract The Bose-Hubbard model is used to study study bosons in optical lattices.
