Summary
The authors demonstrated a programmable quantum processor using reconfigurable arrays of neutral atoms that operates on encoded logical qubits rather than physical ones. They ran error-correcting codes, performed logical entangling operations and algorithms on dozens of logical qubits, and showed that increasing code distance improved logical performance. The work is a key step toward fault-tolerant quantum computation with atom arrays.
Key findings
- Operated up to 48 logical qubits using reconfigurable neutral-atom (Rydberg) arrays
- Performed fault-tolerant logical operations and showed improved fidelity with larger code distance
- Executed logical-level algorithms and complex circuits with hundreds of transversal gates
