Rutgers and IBM Researchers Advance Quantum Computing with Self-Correcting Systems
Researchers from Rutgers, IBM, and collaborating institutions have demonstrated a significant advancement in quantum computing by enabling a quantum computer to monitor and correct its own errors in real-time. This experiment, conducted on a 156-qubit IBM Quantum Heron processor, involved programming the system to alternate between 'scrambler' tasks, which introduce chaos, and 'reset' tasks, which check and correct individual qubits. The team successfully performed nearly 5,000 operations linking pairs of qubits and an equal number of checks and resets, marking the largest successful demonstration of this approach to date. This capability is crucial for developing fault-tolerant quantum computers, which can maintain accurate computations despite the inherent fragility and error-proneness of qubits. The study also confirmed a theoretical prediction, showing that as the frequency of checks and resets increased, the system abruptly shifted from a chaotic state to a controllable, orderly one, akin to a phase t...
