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.

Electro-optical circuit for performing topological quantum computation

A system comprising a nonlinear medium (NLM), an optical transduction module, a dual homodyne detector and a processor is provided. The NLM receives at least a pump beam and issues the pump, probe and conjugate beams, where the beams are linearly polarized. Optics route the probe, the conjugate or both beams to the sample. The sample imparts polarization rotation to light that interacts therewith. The optical transduction module imparts to the interacted light an optical phase shift that is a 1:1 transduction of the polarization rotation, where at least one of the probe light or the conjugate light carries the imparted optical phase shift. The processor obtains the optical-phase shift based on respective detection signals from the dual homodyne detector and determines, based on the obtained optical-phase shift, at least one of a Faraday polarization rotation, a Kerr polarization rotation or a spin noise spectrum.
