Primitive quantum gates for an discrete subgroup: Binary tetrahedral

EJ Gustafson, H Lamm, F Lovelace, D Musk - Physical Review D, 2022 - APS
We construct a primitive gate set for the digital quantum simulation of the binary tetrahedral
(BT) group on two quantum architectures. This non-Abelian discrete group serves as a crude …

Quantum error thresholds for gauge-redundant digitizations of lattice field theories

M Carena, H Lamm, YY Li, W Liu - Physical Review D, 2024 - APS
In the quantum simulation of lattice gauge theories, gauge symmetry can be either fixed or
encoded as a redundancy of the Hilbert space. While gauge-fixing reduces the number of …

Lattice regularizations of vacua: Anomalies and qubit models

M Nguyen, H Singh - Physical Review D, 2023 - APS
Anomalies are a powerful way to gain insight into possible lattice regularizations of a
quantum field theory. In this work, we argue that the continuum anomaly for a given …
