Abstract:
Systems and techniques that facilitate quantum tuning via permanent magnetic flux elements are provided. In various embodiments, a system can comprise a qubit device. In various aspects, the system can further comprise a permanent magnet having a first magnetic flux, wherein an operational frequency of the qubit device is based on the first magnetic flux. In various instances, the system can further comprise an electromagnet having a second magnetic flux that tunes the first magnetic flux. In various cases, the permanent magnet can comprise a nanoparticle magnet. In various embodiments, the nanoparticle magnet can comprise manganese nanoparticles embedded in a silicon matrix. In various aspects, the system can further comprise an electrode that applies an electric current to the nanoparticle magnet in a presence of the second magnetic flux, thereby changing a strength of the first magnetic flux.
