IBM and the University of Chicago demonstrated quantum advantage by performing a computation infeasible for classical supercomputers.
The research team used a novel error-correction method to encode 70 logical qubits. These qubits completed the complex calculation in approximately 15 minutes.
The technique enables error detection during processing to ensure computational accuracy. The logical qubits achieved an error rate 10 times lower than the underlying physical qubits.
This achievement marks a significant step toward building fault-tolerant quantum machines for real-world applications.
