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 qubits, keeping the gauge redundancy can provide code space to mitigate and correct quantum errors by checking and restoring Gauss's law. In this work, we consider the correctable errors for generic finite gauge groups...
The Sachdev-Ye-Kitaev (SYK) model is a fermionic model with $N$-flavors in $(0+1)$-dimensions that has holographic properties and saturates the Chaos bound in the large $N$, and low-temperature limit, where the model gains an approximate conformal symmetry. We propose an improved resource scaling $\mathcal{O}(N^5J^2t^2/\epsilon)$, and show results from noisy quantum hardware for $N=6,8$. In...
A significant challenge in the detection of meV-scale rare events is demonstrating sufficiently low energy detection thresholds in order to detect recoils from light dark matter particles. Many detector concepts have been proposed to achieve this goal, which often include novel detector target media or sensor technology. A universal challenge in understanding the signals from these new...
