Rutgers And IBM Demonstrate Real-Time Control Across 100 Qubits

Researchers from Rutgers, IBM and collaborating institutions demonstrated real-time quantum feedback on up to 100 qubits, using repeated measurements and resets to control chaotic behavior. The experiment used a 156-qubit IBM Heron processor to perform nearly 5,000 two-qubit operations and nearly 5,000 measurements and resets while the system continued running. The researchers observed a sharp transition from chaos to control when resets outpaced scrambling, confirming theoretical predictions and demonstrating a capability needed for future fault-tolerant quantum computers. PRESS RELEASE — Researchers from Rutgers, IBM and collaborating institutions have shown that a quantum computer can check what is happening inside it and respond while it is running, repeatedly resetting parts of the system to bring chaotic behavior under control. The advance is a critical…
