Quantum Computer Systems for Scientific Discovery
Yuri Alexeev, Dave Bacon, Kenneth R. Brown +21
The great promise of quantum computers comes with the dual challenges of building them and finding their useful applications. We argue that these two challenges should be considere…
Systematically Localizable Operators for Quantum Simulations of Quantum Field Theories
Natalie Klco, Martin J. Savage
Correlations and measures of entanglement in ground state wavefunctions of relativistic quantum field theories are spatially localized over length scales set by the mass of the lig…
Sparsening Algorithm for Multi-Hadron Lattice QCD Correlation Functions
W. Detmold, D. J. Murphy, A. V. Pochinsky +3
Modern advances in algorithms for lattice QCD calculations have steadily driven down the resources required to generate gauge field ensembles and calculate quark propagators, such…
SU(2) non-Abelian gauge field theory in one dimension on digital quantum computers
Natalie Klco, Jesse R. Stryker, Martin J. Savage
An improved mapping of one-dimensional SU(2) non-Abelian gauge theory onto qubit degrees of freedom is presented. This new mapping allows for a reduced unphysical Hilbert space. In…
Minimally-Entangled State Preparation of Localized Wavefunctions on Quantum Computers
Natalie Klco, Martin J. Savage
Initializing a single site of a lattice scalar field theory into an arbitrary state with support throughout the quantum register requires entangling gates on a…
Status and Future Perspectives for Lattice Gauge Theory Calculations to the Exascale and Beyond
Bálint Joó, Chulwoo Jung, Norman H. Christ +4
In this and a set of companion whitepapers, the USQCD Collaboration lays out a program of science and computing for lattice gauge theory. These whitepapers describe how calculation…
