A modular atomic processor with 500,000 qubits factors 2048-bit RSA numbers in roughly the same time as a single large module when inter-module Bell-pair communication runs at 10^5 per second.
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 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.
Neutral-atom processor integrates atom motion with in-place entanglement to cut logical overhead, shown in Shor's variant, CX ladders, and [[16,4,4]] code experiments with 2-8x error improvements.
