Rutgers and IBM researchers used repeated measurements and resets to control quantum chaos across up to 100 physical qubits. The experiment tests feedback operations needed for more reliable computing.
A quantum computer is chaos, which we are forced to control. But how? Researchers have shown that this is possible even while its processor is running. In an experiment involving up to 100 qubits, regular measurements and subsequent resets allowed the entire system to steer toward the desired state.
