We propose a scheme for the use of magnetic force microscopy to manipulate Majorana zero modes emergent in vortex cores of topological superconductors in the Fe(Se,Te) family. We calculate the pinning forces necessary to drag two vortices together and the resulting change in current and charge density of the composite fermion. A possible algorithm for measuring and altering Majorana pair parity is demonstrated.

  1. Vortex Majorana braiding in a finite time

    cond-mat.supr-con 2019-08 conditional novelty 6.0 of 10

    Moving a central vortex along a short triangular path for precisely chosen times implements the braiding gate on three exterior vortex Majoranas without physically exchanging them.

  2. Majorana Edge Modes as Quantum Memory for Topological Quantum Computing

    cond-mat.mes-hall 2025-05 conditional novelty 5.0 of 10

    Simulations show that storing qubits in Majorana edge modes and executing gates with vortex-core Majorana zero modes realizes Z, X, and approximate Hadamard gates in a 2D topological superconductor.
