Quantum Monte Carlo Quantum Monte Carlo (QMC) is a class of stochastic algorithms that use the Monte Carlo technique to compute properties of quantum systems. The stochasticity means that instead 2015-12-10 Data corresponding to the results from the paper "Strategies for solving the Fermi-Hubbard model on near-term quantum computers" by Chris Cade, … 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. 2020-10-01 Data corresponding to the results from the paper "Strategies for solving the Fermi-Hubbard model on near-term quantum computers" by Chris Cade, Lana Mineh, … Proposed by Richard Feynman in 1982 [1], a quantum computer harnessing the power of quantum-mechanical phenomena, such as entanglement and superposition promises to solve certain problems much more quickly than a classical computer that is constructed by capac- 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 . 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.

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. 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.

Our results showed that LDCA has the potential to accurately described the exact ground state of strongly correlated fermionic systems on a quantum processor. Quantum circuits based only on matchgates are able to perform nontrivial (but not universal) quantum algorithms. Because matchgates can be mapped to non-interacting fermions, these circuits can be efficiently simulated on a classical computer. One can perform universal quantum computation by adding any nonmatchgate parity-preserving gate, implying that interacting fermions are natural 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 We discuss quantum simulation of the fermionic model by a quantum computer, which is expressed in the language and algebra of quantum spin-1/2 objects Pauli algebra.

Bose-Hubbard model can be simulated on a quantum computer and can simulate arbitrary quantum computa-tions, the complexity of simulating the model is therefore precisely the power of quantum computation. In this article, we prove an analogous result for the Fermi-Hubbard model { a broadly applicable model with 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. 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.
