Benchmarking a randomized quantum algorithm for estimating expectation values of molecular observables
Anna Schroeder, Gian-Luca R. Anselmetti, Matthias Degroote +5
Randomized quantum algorithms for the estimation of expectation values of molecular observables offer a promising route to early fault-tolerant quantum advantage by trading circuit…
Benchmarking a machine-learning differential equations solver on a neutral-atom logical processor
Pauline Mathiot, Elio Garnaoui, Axel-Ugo Leriche +37
We report on a performance comparison between physical and logical computations on a prototypical machine-learning application: solving differential equations using quantum kernel…
One-to-one quantum simulation of a frustrated magnet with 256 qubits
Lucas Leclerc, Sergi Julià-Farré, Gabriel Silva Freitas +33
Analog quantum simulators offer a powerful microscopic probe of quantum many-body systems, yet have largely been benchmarked against model Hamiltonians rather than real materials.…
Quantum simulation of general spin-1/2 Hamiltonians with parity-violating fermionic Gaussian states
Michael Kaicher, Joseph Vovrosh, Alexandre Dauphin +1
We introduce equations of motion for a parity-violating fermionic mean-field theory (PV-FMFT): a numerically efficient fermionic mean-field theory based on parity-violating fermion…
Simulating dynamics of the two-dimensional transverse-field Ising model: a comparative study of large-scale classical numerics
Joseph Vovrosh, Sergi Julià-Farré, Wladislaw Krinitsin +11
The quantum dynamics of many-qubit systems is an outstanding problem that has recently driven significant advances in both numerical methods and programmable quantum processing uni…
Generating Approximate Ground States of Strongly Correlated Quantum Many-Body Systems Through Quantum Imaginary Time Evolution
Michael P. Kaicher, Florian Dommert, Christopher Wever +2
Most quantum algorithms designed to generate or probe properties of the ground state of a quantum many-body system require as input an initial state with a large overlap with the d…
Fault-tolerant quantum simulation of materials using Bloch orbitals
Nicholas C. Rubin, Dominic W. Berry, Fionn D. Malone +8
The simulation of chemistry is among the most promising applications of quantum computing. However, most prior work exploring algorithms for block-encoding, time-evolving, and samp…
Quantum-enhanced quantum Monte Carlo: an industrial view
Maximilian Amsler, Peter Deglmann, Matthias Degroote +10
In this work, we test a recently developed method to enhance classical auxiliary-field quantum Monte Carlo (AFQMC) calculations with quantum computers against examples from chemist…

Michael P. Kaicher, Davide Vodola, Simon B. Jäger
We numerically study the one-dimensional long-range Transverse Field Ising Model (TFIM) in the antiferromagnetic (AFM) regime at zero temperature using Generalized Hartree-Fock (GH…
Low-rank decomposition for quantum simulations with complex basis functions
Michael P. Kaicher
Low-rank decompositions to reduce the Coulomb operator to a pairwise form suitable for its quantum simulation are well-known in quantum chemistry, where the underlying basis functi…
Algorithm for initializing a generalized fermionic Gaussian state on a quantum computer

We present explicit expressions for the central piece of a variational method developed by Shi et al. which extends variational wave functions that are efficiently computable on cl…
Roadmap for quantum simulation of the fractional quantum Hall effect
Michael Kaicher, Simon Balthasar Jäger, Pierre-Luc Dallaire-Demers +1
A major motivation for building a quantum computer is that it provides a tool to efficiently simulate strongly correlated quantum systems. In this work, we present a detailed roadm…
Benchmarking non-simulable quantum processes via symmetry conservation
Tobias Chasseur, Felix Motzoi, Michael Kaicher +2
As quantum devices scale up, many-body quantum gates and algorithms begin to surpass what is possible to simulate classically. Validation methods which rely on such classical simul…
