Abstract

A method for quantum error detection and/or correction according to a quantum error correction code that comprises at least one stabilizer operator acting on at least two data qubits (11), the method comprising: providing a quantum hardware (100, 100', 1000, 1000a, b, c, d, e) which comprises the at least two data qubits (11), a syndrome qubit (12a, b) and a multiqubit coupler (1) for the qubits (11, 12a, b); operating the qubits (11, 12a, b) and the multiqubit coupler (1) according to a syndrome measurement circuit associated with the at least one stabilizer operator to thereby retrieve an error syndrome of a quantum state of the data qubits (11) associated with the at least one stabilizer operator.
