Briefings

Researchers from Rutgers, IBM, and collaborators successfully demonstrated real-time quantum feedback control on up to 100 qubits using the IBM Heron processor. By performing nearly 5,000 two-qubit operations and measurements while the system ran, they observed a sharp phase transition from chaos to control when reset operations outpaced scrambling. This experiment confirmed theoretical predictions about how order emerges from disorder in quantum systems, providing a critical step toward fault-tolerant quantum computers that can correct errors dynamically during computation.

Key points

• Researchers from Rutgers, IBM, and collaborating institutions demonstrated real-time quantum feedback control on up to 100 qubits using the IBM Heron processor.
• The experiment performed nearly 5,000 two-qubit operations and measurements while the system continued running, showing a sharp transition from chaos to control when resets outpaced scrambling.

Context

This breakthrough represents a critical advancement in quantum computing, as it confirms the ability to dynamically correct errors during computation. The study, published in Nature Physics, validates the feasibility of fault-tolerant quantum computers that can maintain stability against quantum noise and errors while performing complex calculations.

Limitations

The evidence is limited to a single experiment conducted on the IBM Heron processor with a 156-qubit system. The study does not provide data on scalability across larger systems, long-term stability of the feedback mechanism, or the specific hardware requirements for fault-tolerant operation beyond the tested conditions.
