Entanglement stabilization using ancilla-based parity detection and real-time feedback in superconducting circuits

The long-term success of quantum computers relies on the ability to perform fault-tolerant quantum computations using quantum error correction. In this approach, errors are detected through the repeated measurement of multi-qubit parity operators and corrected using feedback operations conditioned on the measurement outcomes. In the work [Andersen et.al., npj Quantum Info 5, 69 (2019)], we demonstrate, for the first time with superconducting qubits, all major ingredients for performing quantum error correction implemented simultaneously with the same setup.
