The Utility of Sparse Error Detection in Quantum Simulations
Henry Froland, Dorota M. Grabowska, Sebastian Grieninger +8
The recent success of error detecting codes points toward their potential application to fault-tolerant simulations of nature. In this work, we examine the utility of sparse error…
Realizing Error Suppression in Partially Fault-Tolerant Quantum Simulations with IBM Quantum Computers
Henry Froland, Dorota M. Grabowska, Sebastian Grieninger +8
Quantum error-detecting codes offer a near-term path for improving the performance of quantum simulations on noisy hardware. Using IBM's superconducting quantum computer ibm_boston…
Measuring Non-Stabilizerness in an SU(2) Lattice Gauge Theory
Henry Froland, Dorota M. Grabowska
One of the goals of quantum simulation is to provide novel insights into quantum systems, such as the gauge theories that are relevant for high-energy and nuclear physics. Recent y…
Simulating Fully Gauge-Fixed SU(2) Hamiltonian Dynamics on Digital Quantum Computers
Henry Froland, Dorota M. Grabowska, Zhiyao Li
Quantum simulations of many-body systems offer novel methods for probing the dynamics of the Standard Model and its constituent gauge theories. Extracting low-energy predictions fr…
Sequency Hierarchy Truncation (SeqHT) for Adiabatic State Preparation and Time Evolution in Quantum Simulations
Zhiyao Li, Dorota M. Grabowska, Martin J. Savage
We introduce the Sequency Hierarchy Truncation (SeqHT) scheme for reducing the resources required for state preparation and time evolution in quantum simulations, based upon a trun…
A Fully Gauge-Fixed SU(2) Hamiltonian for Quantum Simulations
Dorota M. Grabowska, Christopher F. Kane, Christian W. Bauer
We demonstrate how to construct a fully gauge-fixed lattice Hamiltonian for a pure SU(2) gauge theory. Our work extends upon previous work, where a formulation of an SU(2) lattice…
