ELECTRO-OPTICAL CIRCUIT FOR PERFORMING TOPOLOGICAL QUANTUM COMPUTATION

A quantum processing device having a type II superconducting medium is provided. Majorana-carrying vortices may be created at some of the defects in the medium by a magnetic flux source. Once created, one or more vortices may be depinned from its departure location, dragged through the medium and repined at a destination location, respectively. One or more laser beams may be respectively used for moving the vortices. The power of the laser beams may be independently controlled. The vortices may be moved for readout and/or for computation, as needed, such as for providing quantum computational gates.
