The Tavis-Cummings interaction plus global J_z restricts unitaries on n>2 qubits due to an accidental symmetry; adding J_z^2 breaks the symmetry and achieves semi-universality for symmetry-respecting operations up to center constraints.

NDAR, a heuristic that turns device noise into a resource, is generalized to integer-domain optimization; qudit-native encodings are argued to be the best fit because their all-zeros attractor is always feasible and their gauge freedom is maximal.
CV-ADAPT-VQE with tailored symmetry-preserving pools achieves significantly shallower circuits than Hamiltonian-based VQE for bosonic lattice models in GPU classical simulations.
A programmable 2D toric oscillator network enables efficient routing for bivariate bicycle LDPC codes, reducing long-range couplers to O(sqrt(n)) and achieving 3.06% logical error rate per cycle in simulations for the [[18,4,4]] code.
Proposes and models a single-shot conditional displacement gate between a trapped atom and traveling light pulse via cavity mediation, including loss effects for hybrid quantum information processing.
Experimental demonstration of 14.6 dB squeezing amplification in a weak Kerr nonlinear superconducting cavity using Trotterized displacements for Fock states up to N=6.
Bosonic Fock encoding in a cavity, driven by SNAP and displacement pulses, produces neutrino oscillation probabilities that match theoretical predictions for two- and three-flavor cases.
The paper reviews advances in quantum simulation of out-of-equilibrium dynamics in gauge theories, covering particle production, string breaking, thermalization, and related phenomena.
