Physicists Develop Error-Correcting Schrödinger’s Cat

Physicists from the Department of Physics and the Department of Applied Physics at Yale University, the Paul Scherrer Institute and Inria Paris have developed an error-correcting cat — a new device that combines the Schrödinger’s cat concept of superposition with the ability to fix some of the trickiest errors in a quantum computation

(...) quantum information bits — qubits — are subject to both bit-flips and phase-flips, in which a qubit randomly flips between quantum superpositions — when two opposite states exist simultaneously. Until now, quantum researchers have tried to fix errors by adding greater redundancy, requiring an abundance of physical qubits for each effective qubit.
