A major obstacle holding back useful large-scale quantum computing is the difficulty in detecting and correcting errors that arise during operations due to noise, imperfect control signals, and other sources. When an error happens, it can flip the value of a sensitive quantum bit, or qubit, from 1 to 0 or vice versa. More qubits flipping leads to accumulating errors that can ultimately result in miscalculations.Now, researchers in Australia say they have devised a method of encoding quantum info...
