Description |
For Topological Quantum Computation non abelian anyons can be made up of unpaired Majorana fermions. We study a simple one dimensional model XY-Ising model where unpaired Majorana modes can be created and manipulated. Further, we showed that a Qubit made up of degenerate unpaired Majorana modes of the model are protected from decoherence by environmental perturbations. Physical realization of the model using Josephson junction quantum circuit has also been achieved. |
