Neutral-atom system delivers state-of-the-art CZ gate fidelity of 99.854% (99.941% postselected) and demonstrates coherent rearrangement for nonlocal quantum circuits.
Loss biasing turns Rydberg errors into erasures in neutral-atom QEC, restoring fault-tolerant Pauli error scaling and enabling optimal erasure scaling with loss-aware decoding for shorter cycles.
A new decoder exploiting correlated atom loss in surface codes raises the loss threshold from 3.2% to 4% and cuts logical errors by up to 10x for neutral-atom processors.
A modified asymmetric Rydberg gate protocol with target detuning and optimized phase waveforms achieves fidelity within a factor of 2.39 of the Rydberg lifetime limit outside the blockade regime.
A blockade-restricted long-range model for Rydberg-cavity systems yields a distinct blockaded ferromagnetic/superradiant phase at equilibrium and long-range many-body scars with logarithmic entanglement dynamics out of equilibrium.
EIT cooling with fluorescence imaging achieves 99.7% readout fidelity and 98.2% survival for 87Rb atom arrays in 2.3 G fields, validated up to 10 G.
