Encoding strategies are presented for both surface codes and high-rate codes, with corresponding performance analyses. We expect this milestone result to significantly advance the era of megaquop-scale quantum computing. arxiv.org/abs/2509.18294

Here, QuEra’s research team introduces a transversal STAR architecture for small-angle magic state generation with neutral atoms. They demonstrate that fault-tolerant simulations with over a million T-gates could be achieved with only ten thousand qubits at a physical error rate of 0.1%.

While this is usually achieved through magic state distillation or cultivation, certain resource states could potentially be synthesized more efficiently in a semi–fault-tolerant way, accelerating our ability to perform complex workflows in fields such as materials simulation.

Simulations show >100× cost reduction vs. leading approaches.
What once seemed to need millions of qubits may now work with ~10,000 physical qubits at ~0.1% error rates.

Why neutral atoms?
Their reconfigurable, long-range links let us run transversal operations across the whole code—no routing detours like in fixed layouts.
Hardware + architecture, co-designed.

How it works:
• Use operations error correction handles really well
• Generate small-angle magic states with simple procedures, where errors naturally shrink as the angle gets smaller

In a new paper with Los Alamos National Labs (🔗 buff.ly/rEnmTZf), we propose a different path:
✨ The transversal STAR architecture ✨
It cuts overhead dramatically and makes large-scale quantum simulation achievable much sooner.

These results underscore the urgency for governments, HPC leaders, and enterprises to adapt their quantum strategies to an accelerating horizon for fault tolerance.

Highlights:
• Reduced runtime overhead: AFT slashes the cost of error correction by a factor of d.
• By combining transversal operations with correlated decoding, AFT maintains exponential error suppression while dramatically speeding up computations.

They prepare and characterize nontrivial entangled states using variational methods, and demonstrate the state preparation using real neutral-atom hardware.
