The toroidal carbon nanotube interferometer coupled with Majorana fermions is considered.
The terminal current and shot noise have been investigated through equation of motion method.
The Andreev and cross-Andreev reflections contribute to the current and shot noise.
The enhancement of shot noise is generated by the application of Majorana fermions.
The periodic oscillations versus Aharonov–Bohm flux exhibit the controlling of Majorana fermions.
