Quantum Algorithms for Simulating the Lattice Schwinger Model
Alexander F. Shaw, Pavel Lougovski, Jesse R. Stryker +1
The Schwinger model (quantum electrodynamics in 1+1 dimensions) is a testbed for the study of quantum gauge field theories. We give scalable, explicit digital quantum algorithms to…
Loop, String, and Hadron Dynamics in SU(2) Hamiltonian Lattice Gauge Theories
Indrakshi Raychowdhury, Jesse R. Stryker
The question of how to efficiently formulate Hamiltonian gauge theories is experiencing renewed interest due to advances in building quantum simulation platforms. We introduce a re…
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…
Solving Gauss's Law on Digital Quantum Computers with Loop-String-Hadron Digitization
Indrakshi Raychowdhury, Jesse R. Stryker
We show that using the loop-string-hadron (LSH) formulation of SU(2) lattice gauge theory (arXiv:1912.06133) as a basis for digital quantum computation easily solves an important p…
Oracles for Gauss's law on digital quantum computers
Jesse R. Stryker
Formulating a lattice gauge theory using only physical degrees of freedom generically leads to non-local interactions. A local Hamiltonian is desirable for quantum simulation, and…
Gauss's Law, Duality, and the Hamiltonian Formulation of U(1) Lattice Gauge Theory
David B. Kaplan, Jesse R. Stryker
Quantum computers have the potential to explore the vast Hilbert space of entangled states that play an important role in the behavior of strongly interacting matter. This opportun…
