Where Atom Loss Lands Matters: Decoder-Aware Risk Deposition in Neutral-Atom QEC
A preprint on arXiv quant-ph investigates how the spatial location of atom loss affects decoding in neutral-atom quantum error correction. It proposes a decoder-aware approach to risk deposition that accounts for where losses occur rather than treating them uniformly.

If decoder-aware atom-loss placement is validated, it could allow near-term neutral-atom QEC experiments to tolerate higher loss rates or operate with fewer overhead qubits by concentrating losses in locations the decoder handles best.
Neutral-atom platforms already support reconfigurable tweezers and loss detection; the main open question is whether making loss location a controllable design parameter can reduce logical error rates without full fault tolerance.
