1. A quantum processing device comprising:
a type II superconducting medium comprising a plurality of defects;
a magnetic flux source configured to produce, during operation of the quantum processing device, a magnetic flux that induces, within the type II superconducting medium, vortices pinned at locations of some of the defects, such that the vortices are separated from each other based on a vortex distribution, wherein two or more vortices are used to enact quantum computational gates of the quantum processing device;
a laser source configured to provide two or more laser beams with controllable power; and
a beam-steering module configured to
redirect the two or more laser beams to departure locations of two or more vortices while the two or more laser beams are provided with a first power that causes unpinning of the two or more vortices from the departure locations, respectively, and allows the two or more laser beams to drag the unpinned vortices through the type II superconducting medium,
sweep the two or more laser beams along respective paths from the departure locations to destination locations of the two or more vortices, and
redirect the two or more laser beams to the destination locations while the two or more laser beams are provided with a second power smaller than the first power that causes pinning of the dragged vortices.
