  Zero--energy Majorana quasiparticles can be induced at the edge of a low
dimensional systems. Non--Abelian statistics of this state makes it a good
candidate for the realization of quantum computing. From the practical point of
view, it is crucial to obtain an intentional creation and manipulation of this
type of bound states. Here, we show such a possibility in a setup of quantum
nanoring in which we specify a quantum dot region via electrostatic means.
States in such quantum dot can lead to the emergence of Andreev and Majorana
bound states in investigated system. We study the differences between those
bound states and the possibility of their manipulation. Moreover, exact
calculation method for spectral function has been proposed, which can be used
to discuss the bound states influence on band structure of proposed system.
Using this method, it can be shown that the Majorana bound states, induced at
the edge of the system, present themselves as a dispersionless zero--energy
band.
