Competition between intra-species repulsion and inter-species attraction in dual-species Rydberg chains induces real-space dynamical fragmentation with coexisting frozen and oscillatory sectors.
Analog quantum kernels with operational noise outperform noiseless versions in benchmarking and non-Markovianity estimation due to increased expressivity and model complexity.
A 256-qubit Rydberg simulator quantitatively reproduces the magnetization curves and antiferromagnetic transition of TmMgGaO4 while revealing thermalization after quenches.
Global multiqubit Rydberg gates enable break-even measurement-free QEC and lower-shuttling Floquet codes in neutral-atom hardware.
Demonstrates a quantum wire encoding using Rydberg atom chains to solve MWIS and QUBO problems on neutral atom arrays with reduced ancilla overhead and experimental validation.
A divide-and-conquer heuristic enables solving MWIS instances from molecular docking with graphs of 225-585 vertices on neutral-atom quantum emulators, outperforming greedy baselines and recovering provably optimal solutions on some instances.
Random global pulses in Rydberg chains generate states with Haar-like statistics at long times for weak interactions, while optimal control prepares generic symmetric states with infidelities from 10^{-5} to 3e-2 for 9 spins, worsening with entanglement entropy.
