Demonstrating real-time and low-latency quantum error correction with superconducting qubits

Nature Communications, Published online: 01 June 2026; doi:10.1038/s41467-026-73331-6 The authors report real-time quantum error correction on Rigetti’s Ankaa-2 by integrating a scalable FPGA decoder into the control stack achieving sub-1 μs mean decoding per round and 9.6 us feedback latency. This work provides a concrete advancement on scalable fault-tolerant computing
