  In this work, we study the bound states in the continuum (BICs) in a system
formed by a triple quantum dot array embedded between two one-dimensional
topological superconductors, both hosting Majorana bound states (MBSs) at its
ends. The results show the formation of BICs with topological characteristics
due to the presence of MBSs. The latter is a consequence of the interplay
between the BIC arising from quantum dots states by means of energy level
symmetry breaking through gate voltages, and MBSs leaked into the quantum dots.
The BIC is not observed when both TSCs are in long wire limit, i. e. for
vanishing inter MBSs coupling, while it projects into the electronic
transmission whenever the inter MBSs couplings are away from zero, regardless
if they are different and/or the phase difference between both TSCs. We study
the behavior of BICs poisoned by MBSs as a function of the parameters that are
controlling the system. We believe our findings could be useful to implement a
protection tool for BICs using MBSs based on tunable gate voltages.
