Two matched-filter algorithms for neutral-atom qubit readout reduce measurement errors by 32-43% versus Gaussian thresholds and use 100x fewer parameters than CNNs while remaining scalable.
Gravitational waves induce long-range dissipative couplings among atoms in ordered arrays via the EM vacuum, producing a distinct superradiant photon emission shifted by the GW frequency and persisting under disorder.
Generalized Krylov complexity predicts the minimum time to realize target operations in analog quantum simulators such as Rydberg atom arrays.
A family of quantum LDPC codes with encoding rates exceeding 1/2 achieves logical error rates of 10^{-13} per round on atom arrays under 0.1% circuit noise using hierarchical decoding.
A multi-atom Rydberg gate with N ancillae enables N-fold photon collection for fast neutral-atom measurement, achieving infidelity below 10^{-3} in 6 μs with N=5 in Cs-Rb simulations.

A counterdiabatic symmetric Rydberg-blockade CZ gate scheme for neutral atoms that reduces operation time versus prior adiabatic protocols, provides analytical pulse profiles, and avoids intrinsic single-qubit phase shifts in single-photon excitation.

Classical kernelisation fully reduces many small and sparse unit-disk graphs for MIS and MWIS native to Rydberg arrays, but dense graphs retain finite irreducible kernels, with vertex weights increasing reducibility and extended interaction ranges suppressing it.
