For the first time, researchers distilled high-fidelity "magic states" within logical qubits on a neutral-atom Gemini computer—crucial for enabling non‑Clifford gates and universal, fault‑tolerant quantum computation
Using distance‑3 and distance‑5 color codes, five imperfect states were refined into a single higher‑quality magic state. Output fidelity exceeded inputs, showing quadratic error suppression in logical qubits.
Gemini’s atomic arrays enabled parallel encoding of up to five logical qubits with dynamic reconfiguration. The setup illustrates neutral atoms’ scalability for advanced, error‑corrected quantum processing.
This experiment delivered the missing ingredient—magic-state factories within logical layers—enabling execution of complex algorithms and marking a pivotal step toward scalable, useful quantum computers.
