Gauge protection in non-abelian lattice gauge theories

Jad C. Halimeh et al.

Summary: Researchers demonstrate how non-abelian gauge invariance can be reliably controlled using energy protection terms, protecting the target gauge sector from unitary gauge-breaking errors. They also show that in certain cases, single-body protection terms can robustly suppress gauge violations at all evolution timescales, exhibiting the emergence of an adjusted gauge theory.

Cold atoms meet lattice gauge theory

Monika Aidelsburger et al.

Summary: This article discusses the replacement of fermionic matter with bosonic matter in quantum field theory models relevant for particle physics. The motivation behind this substitution is that bosons are more accessible and easier to manipulate for experimentalists, which leads to new physics and novel phenomena. The article also explores atomic simulators of paradigmatic models of particle physics theory. It reviews the activities related to quantum simulations for lattice field theories performed by the Quantum Optics Theory group at ICFO and their collaborators from 19 institutions worldwide. Additionally, the article briefly describes efforts to design experimentally friendly simulators for these and other models relevant for particle physics.

Quantum simulation of lattice gauge theories in more than one space dimension-requirements, challenges and methods

Erez Zohar

Summary: The field of quantum simulation of lattice gauge theories, which aims to implement simulators of gauge theories with quantum platforms, has experienced rapid development. It has gained interest not only from the quantum information and technology communities, but also from particle and nuclear physicists who see it as a tool for tackling hard, non-perturbative gauge theory problems. More and more experiments have been reported, mainly focusing on 1 + 1 dimensional physics.

Thermalization dynamics of a gauge theory on a quantum simulator

Zhao-Yu Zhou et al.

Summary: Gauge theories are the foundation of modern physics, and their applications range from elementary particle physics to condensed matter systems. Researchers have performed quantum simulations of a U(1) symmetric gauge field theory and demonstrated emergent irreversible behavior. Their work may enable the investigation of elusive phenomena and pave the way for simulating more complex gauge theories on quantum synthetic matter devices.

Confinement and Mott Transitions of Dynamical Charges in One-Dimensional Lattice Gauge Theories

Matjaz Kebric et al.

Summary: The article discusses the relationship between confinement and translational symmetry breaking in 1D Z(2) lattice gauge theories, showing an exact mapping of Luttinger parameters and predicting the formation of confined mesons in a Mott-insulating state. The metallic state is characterized by hidden off-diagonal quasi-long-range order, offering new insights into the physics of confinement of dynamical charges and potential experimental verification in Rydberg-dressed quantum gases in optical lattices.

Gauge-Symmetry Protection Using Single-Body Terms

Jad C. Halimeh et al.

Summary: This study presents an experimentally friendly method for protecting gauge invariance in U(1) lattice gauge theories against coherent errors, using single-body energy-penalty terms. The method ensures that undesired gauge sectors are inaccessible for exponentially long times, with little dependence on system size. The findings show exponential improvement over previous results and can be implemented in current ultracold-atom analog simulators and digital quantum devices.

Z2 lattice gauge theories and Kitaev's toric code: A scheme for analog quantum simulation

Lukas Homeier et al.

Summary: This work presents a building block for Z(2) lattice gauge theories coupled to dynamical matter, enabling the implementation of the toric code ground state and its topological excitations. The proposal is realized in the second-order coupling regime and is well suited for superconducting qubit implementations. The study outlines a pathway for preparing topologically nontrivial initial states and experimental signatures of the ground-state wave function.
