Optimal and improved gate decompositions for accelerated classical simulation of near-Gaussian fermionic circuits
Beatriz Dias, Jan Lukas Bosse, James R. Seddon
Fermionic Gaussian circuits can be simulated efficiently on a classical computer, but become universal when supplemented with non-Gaussian operations. Similar to stabilizer circuit…
Programmable digital quantum simulation of 2D Fermi-Hubbard dynamics using 72 superconducting qubits
Faisal Alam, Jan Lukas Bosse, Ieva Čepaitė +41
Simulating the time-dynamics of quantum many-body systems was the original use of quantum computers proposed by Feynman, motivated by the critical role of quantum interactions betw…
Fermionic dynamics on a trapped-ion quantum computer beyond exact classical simulation
Faisal Alam, Jan Lukas Bosse, Ieva Čepaitė +37
Simulation of the time-dynamics of fermionic many-body systems has long been predicted to be one of the key applications of quantum computers. Such simulations -- for which classic…
Efficient and practical Hamiltonian simulation from time-dependent product formulas
Jan Lukas Bosse, Andrew M. Childs, Charles Derby +3
In this work we propose an approach for implementing time-evolution of a quantum system using product formulas. The quantum algorithms we develop have provably better scaling (in t…
Dissipative Quantum Gibbs Sampling
Daniel Zhang, Jan Lukas Bosse, Toby Cubitt
Systems in thermal equilibrium at non-zero temperature are described by their Gibbs state. For classical many-body systems, the Metropolis-Hastings algorithm gives a Markov process…
Sketching phase diagrams using low-depth variational quantum algorithms
Jan Lukas Bosse, Raul Santos, Ashley Montanaro
Mapping out phase diagrams of quantum systems using classical simulations can be challenging or intractable due to the computational resources required to simulate even small quant…
Observing ground-state properties of the Fermi-Hubbard model using a scalable algorithm on a quantum computer
Stasja Stanisic, Jan Lukas Bosse, Filippo Maria Gambetta +5
The famous, yet unsolved, Fermi-Hubbard model for strongly-correlated electronic systems is a prominent target for quantum computers. However, accurately representing the Fermi-Hub…
Probing ground state properties of the kagome antiferromagnetic Heisenberg model using the Variational Quantum Eigensolver
Jan Lukas Bosse, Ashley Montanaro
Finding and probing the ground states of spin lattices, such as the antiferromagnetic Heisenberg model on the kagome lattice (KAFH), is a very challenging problem on classical comp…
