Using a 156-qubit IBM Quantum Heron r2 processor, the team demonstrated that mid-circuit measurements — essential for quantum error correction — force other qubits to idle, introducing significant noise. By redesigning error-correction circuitry to reduce idling time, they improved logical qubit survival rates from below 90% to over 96% per error-correction cycle. The findings, published in Nature Communications, provide quantitative benchmarks for the performance requirements of error-checking operations and offer a clearer roadmap for scaling fault-tolerant quantum systems. ## Full article daily.dev links to this article rather than hosting it.
