The development of “fault tolerant” quantum computation, unaffected by noise and decoherence, is one of the fundamental challenges in quantum technology.

One of the approaches currently followed is the realization of “topologically protected” qubits which make use of particles known as anyons, able to encode and manipulate quantum information in a nonlocal manner. An example of such particles are Majorana zero energy modes (MZMs).
In the latest years, the search for MZMs become one of the most intensive activity in condensed matter physics. Several research groups have reported evidences of MZMs in hybrid superconducting devices employing semiconducting nanostructures or topological insulator materials (click here for a review).
2D electron gases (2DEGs) formed at the interface between transition metal oxides, like LAO/STO, possess extraordinary properties, like high-mobility, strong spin-orbit coupling, superconductivity, interfacial 2D-magnetism and topological states. The combination of these properties could lead to the realization of MZMs.
QUANTOX project is committed to the study oxide 2DEGs for the development of a new platform based on oxide nanotechnology, for the realization of topological quantum gates based on MZMs anyons.
