  Majorana bound states emerge in topological superconductors as zero-energy
edge states exhibiting spatial nonlocality. Despite the enormous advances, the
detection of Majorana bound states is still challenging mainly because
topologically trivial Andreev bound states produce similar signatures. In this
work we consider a topological superconductor with Majorana bound states
coupled to quantum dots and investigate the dynamics of their quantum
correlations with the aim to explore their entanglement properties. In
particular, we characterize entanglement by using concurrence and discord,
which are also complemented by the entanglement dynamics and return
probability. We find that Majorana bound states at truly zero energy can
transform an initially entangled system into its classical state, while they
can create maximally entangled states at a finite energy overlap.
Interestingly, we show that the system can generate a maximally entangled state
between MBSs and a quantum dot by simply controlling the Majorana nonlocality.
We demonstrate that these results hold in the scenarios when the initial state
is either maximally entangled or separable, albeit in the latter maximally
entangled states are achieved in the long time dynamics. Furthermore, we
contrast our findings with those produced by a regular fermion and obtain very
distinct entanglement signatures. Our work offers an alternative approach to
characterize Majorana bound states, which can be also useful towards their
utilization for quantum information tasks.
