Stabilizing quantum computers by preventing qubits escaping operational state and disrupting calculations

"leakage occurs when qubit jumps to a higher energy level leaving calculation/ creating noise interfering with neighboring qubits... need for difficult to scale bulky hardware overcome, by moping up errors using specific microwave pulses nudging qubits back into correct energy states without stopping computation... secondary ancilla (helper) qubits detect/ reset errors with microwaves clearing system. 70X more effective, error suppression improves with scaling... large-scale quantum processors"
