Abstract
A controllable magnetic connection element comprising a dilute magnetic semiconductor for connecting topological qubits includes a magnetic connector and a magnet. The magnet is configured to alter a paramagnetic/diamagnetic character of the magnetic connector to control the magnetic connection to allow or prevent the transmission of a spin current between the topological qubits. A method for controlling entanglement between topological qubits includes controlling a magnetic field around a magnetic connection between the topological qubits to interrupt or allow transmission of spin polarised electrons between the topological qubits and thereby entangle or prevent entanglement between them.
