🔬 Top Papers

Quantum Error Correction Below the Surface Code Threshold

• Authors / Affiliation: Google Research (Published in Nature, April 28, 2026)
• Key Contribution: Implementation of two sub-threshold surface code memories on a superconducting processor; achieving exponential reduction in logical error rates.
• Experimental Results: Reduction in logical error per cycle of over 50% as code distance increases; at distance-7, logical lifetime exceeded physical qubit lifetime by more than 2x.
• Significance: This is a critical milestone suggesting the practicality of running large-scale fault-tolerant quantum algorithms. The exponential scaling of logical error suppression proves the viability of commercializing quantum computing.
