Rārangi ihirangi:
- <p>Large-scale mean-field simulations of a 30×30 Rydberg-dressed atom array under a \textbf{single global drive with dynamically modulated spiral phase} reveal autonomous self-organization into an extremely rigid Floquet cat state. The drive phase pattern $\theta(r,\phi,t)$ contains a weak base spiral ($\theta_{\max}{=} \pi/512$) plus quasi-periodic angular frequency modulation $\omega_{\text{ang}}(t)$ with incommensurate components at $2\pi/P_1$ and $4\pi/P_2$. Global phase coherence rises from 0.37 to $>0.999$ within $\sim$600 periods, survives a large transient excursion near period 1700, and then locks above 0.999 for the final 4507+ cycles (total simulation: 5000 periods). The final coherence distribution (period $>1000$) has mean 0.99560 and $\sigma{=}8.07{\times}10^{-3}$. The attractor consists of two degenerate periodic orbits separated by a global $\pi$ phase shift, defining a logical cat qubit. A single global $\pi$-pulse implements logical-$X$ with fidelity $>0.9999$ in the locked regime. No individual addressing, feedback electronics, or mid-circuit measurement is used — the self-tuning emerges purely from many-body Floquet dynamics.</p>
