New Delhi, March 27 -- Bangalore, Karnataka, India- A scalable quantum error correction system has been developed by QpiAI to enable fast, scalable error correction using a rotated surface code architecture. The decoder, based on a union-find algorithm, is designed to operate in real time alongside superconducting qubits and represents a key step toward practical fault-tolerant quantum computing.

The system implements a distance-5 rotated surface code using 49 physical qubits. Each decoder instance runs on a single QpiAI Kaveri QPU, which provides 64 qubits, allowing one decoder instance per chip. The architecture is optimized to support efficient decoding and integration with existing quantum hardware.
