Researchers from IBM, Rutgers University, and other institutions have successfully managed a 100-qubit quantum system in real time. The experiment utilized the IBM Quantum Heron processor, which features 156 qubits in total, with a chain of 100 qubits actively involved in the process.
The team executed approximately 5,000 two-qubit gate operations alongside 5,000 measurements and resets. By alternating between scrambling quantum information and performing targeted resets, the researchers transitioned the system from a chaotic state to a controlled, ordered state, aligning with theoretical predictions.
This achievement represents one of the largest demonstrations of quantum feedback control to date. The technology is considered a critical step toward developing fault-tolerant quantum computers, as it enables real-time error correction and state monitoring during complex computations.
