Theoretical Physics Quantum programming and simulation of the Hubbard model using Q# Henric Hintze SA114X Degree Project in Engineering Physics, First Level 2019-05-21 · The goal is to prepare the ground state of the Hubbard model on a quantum computer. We start from the ground state of the non-interacting model (U = 0), 8 which—in principle—can be prepared efficiently on a quantum computer , and we apply the VHA in order to evolve this state towards , which should be close to the ground state . 2018-11-11 · Abstract: A key goal of digital quantum computing is the simulation of fermionic systems such as molecules or the Hubbard model. Unfortunately, for present and near-future quantum computers the use of quantum error correction schemes is still out of reach. 2019-12-12 · The Fermi-Hubbard model is of fundamental importance in condensed-matter physics, yet is extremely challenging to solve numerically.

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. The e cient simulation of correlated quantum systems is the most promising near-term applica-tion of quantum computers. Here, we present a measurement of the second Renyi entropy of the ground state of the two-site Fermi-Hubbard model on a 5-qubit programmable quantum computer based on trapped ions. 2013-09-02 · Models are abundant in virtually all branches of physics, with some achieving iconic status. The Hubbard model, celebrating its golden jubilee this year, continues to be one of the most popular Hubbard Model Introduction 4.5 t t t t t U Fig. 1: Pictorial representation of the terms in the Hubbard Hamiltonian. Left: The kinetic energy t.Right: The on-site repulsion U. A reasonable thought for the kinetic energy is an expression which destroys a fermion on one Quantum antiferromagnetism (AF) has been an important topicofthetwo-dimensional(2D)stronglycorrelatedsystems for decades. 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.

One can perform universal quantum computation by adding any non-matchgate parity-preserving Keyword Bose-Hubbard model, extended Bose-Hubbard model, compactons, quantum compactons : Abstract The Bose-Hubbard model is used to study bosons in optical lattices. In this the-sis we will use an extended Bose-Hubbard model to study a type of completely localized solutions, called compactons.

## Development of an in vitro model of Toxoplasma gondii cyst formation. tablets and computer monitors) was about a factor of 2 to 3 higher than incandescent become too excited to be trapped by the quantum wells in the semiconductor, where Find this author on PubMed Search for this author on this site Tim Hubbard.

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. 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.

### 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.

The Fermi-Hubbard model is of fundamental importance in condensed-matter physics, yet is extremely challenging to solve numerically.

In this article, we prove an analogous result for the Fermi-Hubbard model { a broadly applicable model with
Quantum phase transitions in the Bose–Hubbard model were experimentally observed by Greiner et al., and density dependent interaction parameters were observed by I.Bloch's group. Single-atom resolution imaging of the Bose–Hubbard model has been possible since 2009 using quantum gas microscopes. 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
A quantum computer with a few tens of qubits could therefore simulate the thermodynamic properties of complex fermionic lattices inaccessible to classical supercomputers.

### The Bose–Hubbard model gives a description of the physics of interacting spinless bosons on a lattice. It is closely related to the Hubbard model which originated in solid-state physics as an approximate description of superconducting systems and the motion of electrons between the atoms of a crystalline solid. The model was first introduced by Gersch and Knollman in 1963 in the context of granular superconductors. The model …
