We consider the Cooper pairing of Dirac electrons and conventional holes that can be engineered in topological the insulator/quantum-well double layer heterostructures. The helical nature of Dirac electrons manifests in the presence of two (almost) degenerate channels for the Cooper pairing. Being stable and matastable, both of these states are characterized by distinct Chern numbers are topological condensates. We discuss possible including chiral states at the domain walls between these states and the ways that they can be engineered.
