Topological quantum computation

Spatially confining topological bound states such as Majorana states or chiral modes in quantum devices implies creating quantum states that are unperturbed by local environment perturbations. This means a substantial decrease in quantum decoherence that haunts quantum computation technologies. We utilize topological materials to propose new robust quantum devices.
