Gauge-Theoretic Origin of Rydberg Quantum Spin Liquids

P. S. Tarabunga et al.

Summary: Recent experiments and numerical simulations have found complementary features of a topological quantum spin liquid, but the mechanism stabilizing this phase is still unclear. In this study, a relation between an Ising-Higgs lattice gauge theory and blockaded models is introduced, which explains the origin of previously observed topological spin liquids. Using exact diagonalization and unbiased quantum Monte Carlo simulations, it is shown that the deconfined phases exist in a broad parameter space and are characterized by a large ground state overlap with resonating valence bond wave functions.

Dynamical Preparation of Quantum Spin Liquids in Rydberg Atom Arrays

Giuliano Giudici et al.

Summary: Recent experiments demonstrate the onset of a topological spin liquid using a programmable quantum simulator based on Rydberg atom arrays. By preparing out-of-equilibrium states using a quasiadiabatic state preparation protocol, robust signatures of topological order emerge. The state preparation protocol can be optimized to target the fixed point of the topological phase, and a two-parameter variational manifold of tensor network states accurately describes the many-body dynamics of the preparation process.

Quantum phases of Rydberg atoms on a kagome lattice

Rhine Samajdar et al.

Summary: Density-matrix renormalization group calculations show a wide variety of complex solid phases and a region with dense Rydberg excitations, large entanglement entropy, and no local order parameter on the kagome lattice of neutral atoms at zero temperature. The regime could contain one or more phases with topological order, as suggested by mapping to the triangular lattice quantum dimer model and theories of quantum phase transitions. These results lay the foundation for theoretical and experimental explorations of crystalline and liquid states using programmable quantum simulators based on Rydberg atom arrays.

Realizing topologically ordered states on a quantum processor

K. J. Satzinger et al.

Summary: The discovery of topological order revolutionized the understanding of quantum matter and laid the theoretical groundwork for quantum error-correcting codes. By preparing the ground state of the toric code Hamiltonian on a superconducting quantum processor, researchers were able to measure topological entanglement entropy and simulate anyon interferometry. Investigating aspects of the surface code, including logical state injection and the decay of nonlocal order parameter, showed the potential of quantum processors in studying topological quantum matter and error correction mechanisms.

Prediction of Tonic Code Topological Order from Rydberg Blockade

Ruben Verresen et al.

Summary: The study demonstrates the realization of Z(2) topological order in a two-dimensional array of Rydberg atoms on the ruby lattice, at specific values of the Rydberg blockade radius. Using numerical density matrix renormalization group method, the phase diagram is obtained, showing the existence of a topological quantum liquid (TQL) with experimental measurement methods proposed. The implications for exploring fault-tolerant quantum memories are also discussed.
