# Fate of Lattice Gauge Theories Under Decoherence

@article{Halimeh2020FateOL, title={Fate of Lattice Gauge Theories Under Decoherence}, author={Jad C. Halimeh and Valentin Kasper and Philipp Hauke}, journal={arXiv: Quantum Gases}, year={2020} }

A major test of the capabilities of modern quantum simulators and NISQ devices is the reliable realization of gauge theories, which constitute a gold standard of implementational efficacy. In addition to unavoidable unitary errors, realistic experiments suffer from decoherence, which compromises gauge invariance and, therefore, the gauge theory itself. Here, we study the effect of decoherence on the quench dynamics of a lattice gauge theory. Rigorously identifying the gauge violation as a…
