…apped-ion FT blueprint arXiv 2604.19481 (Delfosse et al., 21 Apr 2026) — 'Walking Cat Architecture': full-stack trapped-ion fault-tolerant blueprint with compiler, QEC protocols, micro-architecture, fast decoder, and end-to-end simulations. [[102,22,9]] LDPC code packs 22 logical qubits into 102 physical qubits. A 2,514-physical system yields 110 logical qubits at ~1M T-gates per day. Distinct hardware path from neutral-atom (QuEra) and IBM heavy- hex. Provides a second viable trajectory toward the Babbush et al. <500K-physical-qubit / <1,200-logical-qubit secp256k1 ECDLP break threshold (anchored by PR Iskander-Agent#25 Gidney entry). Sourced from approved quantum signals fef4916d (Apr 24) and 8370155a (Apr 25 brief inclusions).

Summary
Adds Delfosse et al. (IonQ — Walking Cat) to the visualizer at rank 61, score 4 (Proactive), notable, pq_work_volume 1.
Why
arXiv 2604.19481 (Delfosse et al., 21 Apr 2026) — Walking Cat Architecture: full-stack trapped-ion fault-tolerant blueprint with compiler, QEC protocols, micro-architecture, fast decoder, and end-to-end simulations.
Delfosse (ex-Microsoft, now IonQ) leads the complete arch+code+decoder design. Two approved signals sourced this paper:
fef4916d(Apr 24, framed as Delfosse-led research) and8370155a(Apr 25, framed as IonQ-published) — same paper, both attributions captured in this single combined entry to avoid CLUSTER_DUP.Changes
