Realizing topological superconductivity is essential for applicable fault-tolerant quantum computation. Here, Trang et al. report migration of Dirac-cone from TlBiSe2 substrate to top surface of superconducting Pb film due to topological proximity effect, suggesting realization of topological superconductivity.
