  Atomic manipulation and interface engineering techniques have provided a
novel approach to custom-designing topological superconductors and the ensuing
Majorana zero modes, representing a new paradigm for the realization of
topological quantum computing and topology-based devices. Magnet-superconductor
hybrid (MSH) systems have proven to be experimentally suitable to engineer
topological superconductivity through the control of both the complex structure
of its magnetic layer and the interface properties of the superconducting
surface. Here, we demonstrate that two-dimensional MSH systems containing a
magnetic skyrmion lattice provide an unprecedented ability to control the
emergence of topological phases. By changing the skyrmion radius, which can be
achieved experimentally through an external magnetic field, one can tune
between different topological superconducting phases, allowing one to explore
their unique properties and the transitions between them. In these MSH systems,
Josephson scanning tunneling spectroscopy spatially visualizes one of the most
crucial aspects underlying the emergence of topological superconductivity, the
spatial structure of the induced spin-triplet correlations.
