The invention relates to a method and an apparatus for detecting a state of a data qubit by means of a parity qubit, wherein both the data qubit and the parity qubit can be moved by a moving means, wherein the distance between the data qubit and the parity qubit is so large that the parity qubit cannot query the state of the data qubit, wherein the distance between the data qubit and the parity qubit is reduced by moving the data qubit along a first path and the parity qubit along a second path until the state of the data qubit can be queried by the parity qubit, characterized in that the first path is longer than the second path and/or that the speed of movement of the parity qubit is greater than the speed of movement of the data qubit.
A method for detecting a faulty state of a data qubit using a parity qubit, wherein at least the parity qubit can be moved by a movement device, wherein a distance between the data qubit and the parity qubit is so large that the parity qubit cannot be entangled with the data qubit, wherein the distance between the data qubit and the parity qubit is reduced by moving the data qubit along a first path and the parity qubit along a second path until the data qubit can be entangled with the parity qubit, characterized in that the second path is longer than the first path and/or in that a speed of movement of the parity qubit is greater than a speed of movement of the data qubit.
An apparatus for performing a method for detecting a faulty state of a data qubit using a parity qubit, comprising data qubits and parity qubits, wherein a movement device is provided, with which the data qubits and the parity qubits can be moved, wherein a distance between the data qubit and the parity qubit can be so large that the parity qubit cannot be entangled with the data qubit, wherein the distance between the data qubit and the parity qubit can be reduced by moving the data qubit along a first path and the parity qubit along a second path until the data qubit can be entangled with the parity qubit, characterized in that the first path is longer than the second path and/or that a speed of movement of the parity qubit can be greater than a speed of movement of the data qubit.
