1. A flux-biasing device comprising:

  • a plurality of magnetic flux generating members (member);

    a detachable platform located external to a package, the package comprising a plurality of qubits of a quantum processor, wherein the plurality of members are installed on the platform, whereina first member of the plurality of members is configured to magnetically interact with a first qubit in the plurality of qubits of the quantum processor such that a first magnetic flux of the first member causes a first change in a first resonance frequency of the first qubit by a first frequency shift value, andeach non-corresponding member of the plurality of members is at least at a threshold distance from qubits corresponding to other members of the plurality of members such that qubits corresponding to other members exhibit less than a threshold value of resonance frequency shift as a result of a magnetic flux of a non-corresponding member.
