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…
Block encoding bosons by signal processing
Christopher F. Kane, Siddharth Hariprakash, Neel S. Modi +2
Block Encoding (BE) is a crucial subroutine in many modern quantum algorithms, including those with near-optimal scaling for simulating quantum many-body systems, which often rely…
Exponential improvements in the simulation of lattice gauge theories using near-optimal techniques
Mason L. Rhodes, Michael Kreshchuk, Shivesh Pathak
We report a first-of-its-kind analysis on post-Trotter simulation of U(1), SU(2) and SU(3) lattice gauge theories including fermions in arbitrary spatial dimension. We provide expl…
Strategies for simulating time evolution of Hamiltonian lattice field theories
Siddharth Hariprakash, Neel S. Modi, Michael Kreshchuk +2
Simulating the time evolution of quantum field theories given some Hamiltonian requires developing algorithms for implementing the unitary operator e^{-iHt}. A variety of techn…
Simulating Scattering of Composite Particles
Michael Kreshchuk, James P. Vary, Peter J. Love
We develop a non-perturbative approach to simulating scattering on classical and quantum computers, in which the initial and final states contain a fixed number of composite partic…
