Building Perfect Quantum Arrays, One Atom at a Time

23.11.2025 by Ray Dalio

The scaling of rearrangement moves, computed via Monte Carlo simulation at zero atom-loss probability, remains consistently near $0.55$ for occupation fractions of $0.5$ and $0.7$, but increases to approximately $0.71$ at higher fill levels, suggesting a shift in the dominant mechanism governing rearrangement as the system approaches saturation.

Researchers have developed a new algorithm that efficiently rearranges neutral atoms, paving the way for more stable and scalable quantum computers.
