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…
Quantum Simulation of Nucleon-Antinucleon Interaction in Large- QCD on an IBM Quantum Nighthawk Processor
Cameron V. Cogburn, Sebastian Grieninger, Dmitri E. Kharzeev
We report a quantum simulation of the nucleon--antinucleon interaction in large- two-dimensional quantum chromodynamics (QCD) on the IBM Quantum Nighthawk processor. In the…
Small behavior in QCD from maximal entanglement and conformal invariance
Sebastian Grieninger, Kun Hao, Dmitri E. Kharzeev +1
Recent evidence suggests that, at small Bjorken , QCD evolution drives the proton into a state of maximal entanglement. If the evolution kernel is assumed to be conformally inva…
Nonlocal Nonstabilizerness from Holographic Schwinger Pair Production
Sebastian Grieninger
We analyze the emergence of nonlocal magic in Schwinger pair creation in strong non-Abelian (chromo)electric fields using holography. The produced quark--antiquark pair is entangle…
The Quantum Complexity of String Breaking in the Schwinger Model
Sebastian Grieninger, Martin J. Savage, Nikita A. Zemlevskiy
String breaking, the process by which flux tubes fragment into hadronic states, is a hallmark of confinement in strongly-interacting quantum field theories. A suite of quantum comp…
