  We investigate dynamical evolution of a topological memory that consists of
two $p$-wave superconducting wires separated by a non-topological junction,
focusing on the primary errors (i.e., qubit-loss) and secondary errors (bit and
phase-flip) that arise due to non-adiabaticity. On the question of qubit-loss
we examine the system's response to both periodic boundary driving and
deliberate shuttling of the Majorana bound states. In the former scenario we
show how the frequency dependent rate of qubit-loss is strongly correlated with
the local density of states at the edge of wire, a fact that can make systems
with a larger gap more susceptible to high frequency noise. In the second
scenario we confirm previous predictions concerning super-adiabaticity and
critical velocity, but see no evidence that the coordinated movement of edge
boundaries reduces qubit-loss. Our analysis on secondary bit flip errors shows
that it is necessary that non-adiabaticity occurs in both wires and that
inter-wire tunnelling be present for this error channel to be open. We also
demonstrate how such processes can be minimised by disordering central regions
of both wires. Finally we identify an error channel for phase flip errors,
which can occur due to mismatches in the energies of states with bulk
excitations. In the non-interacting system considered here this error
systematically opposes the expected phase rotation due to finite size splitting
in the qubit subspace.
