Na ancilla reads Z-parity from four surrounding Cs qubits. No transport. One global Rydberg pulse. Collapses the four spatial zones typically needed for syndrome extraction into one. buff.ly/Qiz06ag

- qLDPC codes in practice have achieved encoding rates around 1/10 or lower. This QuEra preprint pushes above 1/2, co-designed for neutral-atom arrays. [[2304, 1156]] code: 1.3×10^-13 per-logical-per-round at p=0.1%.
- Non-integrable spin chains should diffuse. A Harvard/Berkeley team found KPZ-like transport (z=3/2) surviving to t~1000/J in 2,000-spin simulations. Integrability proximity is the explanation. Rydberg arrays (α=3,6) can probe this directly.
- Quench a 180-qubit spin system on Aquila & it doesn't thermalize on schedule. Instead: stable prethermal regimes, resonant melting when those states break, & a 2D dynamical phase transition with no equilibrium analog. Paper from QuEra + NERSC @ LBNL: buff.ly/HZcAYCD
