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…
Classical shadows for sample-efficient measurements of gauge-invariant observables
Jacob Bringewatt, Henry Froland, Andreas Elben +1
Classical shadows provide a versatile framework for estimating many properties of quantum states from repeated, randomly chosen measurements without requiring full quantum state to…
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…
Entanglement Structure of Non-Gaussian States and How to Measure It
Henry Froland, Torsten V. Zache, Robert Ott +1
Rapidly growing capabilities of quantum simulators to probe quantum many-body phenomena require new methods to characterize increasingly complex states. We present a protocol that…
