  In recent years, various classes of systems were proposed to realize
topological states of matter. One of them are multiterminal Josephson junctions
where topological Andreev bound states are constructed in the synthetic space
of superconducting phases. Crucially, the topology in these systems results in
a quantized transconductance between two of its terminals comparable to the
quantum Hall effect. In this work, we study a double quantum dot with four
superconducting terminals and show that it has an experimentally accessible
topological regime in which the non-trivial topology can be measured. We also
include Coulomb repulsion between electrons which is usually present in
experiments and show how the topological region can be maximized in parameter
space.
