The study shows real-time feedback control of 100 superconducting qubits, with mid-circuit measurements and resets, on IBM's 156-qubit Heron processor. It reports a measured phase transition between chaotic and controlled regimes, backed by shot-level statistics compared against classical noise models. For quantum readers, the relevant point is the experimental validation of non-unitary dynamics and mid-circuit operations at a scale that matters for error-correction research, though the claims are still limited to one hardware platform and one class of circuits.

IBM and Rutgers Control Quantum Chaos Across 100 Qubits on Heron Processor

Quantum Computing ReportOctober 22, 20262 min read

IBM and Rutgers researchers have demonstrated real-time quantum feedback control across 100 qubits on an IBM Quantum Heron processor. Their study, published in Nature Physics, implemented adaptive quantum circuits to validate non-unitary dynamics crucial for scalable quantum error correction. They observed a control-induced phase transition between chaotic and controlled phases, marking a significant step in experimental quantum control and hardware certification.
