Fault-tolerant simulation of Lattice Gauge Theories with gauge covariant codes
Luca Spagnoli, Alessandro Roggero, and Nathan Wiebe
Quantum 10, 1968 () | arXiv:2405.19293 [quant-ph]We show in this paper that a strong and easy connection exists between quantum error correction and Lattice Gauge Theories (LGT) by using the Gauge symmetry to construct an efficient error-correcting code for Abelian \(Z2\) LGTs. We identify the …

Symmetry-protection Zeno phase transition in monitored lattice gauge theories
Matteo M. Wauters, Edoardo Ballini, Alberto Biella, and Philipp Hauke
Phys. Rev. B 111, 094315 () | arXiv:2405.18504 [quant-ph, hep-lat]Quantum measurements profoundly influence system dynamics. They lead to complex nonequilibrium phenomena like the quantum Zeno effect, and they can be used for mitigating errors in quantum simulations. Such an ability is particularly valuable for …

Observation of microscopic confinement dynamics by a tunable topological θ-angle
Wei-Yong Zhang, Ying Liu, and Yanting Cheng et al.
Nat. Phys. 21, 155–160 ()The topological θ-angle is central to several gauge theories in condensed-matter and high-energy physics. For example, it is responsible for the strong CP problem in quantum chromodynamics and can emerge in effective theories of electrodynamics in …
