IBM and Rutgers demonstrate real-time error correction on 100 qubits

Researchers from Rutgers and IBM used the 156-qubit IBM Quantum Heron processor to run a 100-qubit chain that measured and reset qubits mid-computation, suppressing chaotic behavior. Published in Nature Physics, the work shows a clear phase transition from chaos to order once the reset rate passes a threshold.

• Experiment ran on IBM's 156-qubit Heron processor using a chain of 100 connected qubits
• Team performed nearly 5,000 two-qubit operations plus a similar number of measurements and resets
• System stayed chaotic when scrambling exceeded half the time, turning orderly past a reset threshold
• Results matched theoretical predictions and became sharper as system size grew
