Abstract: We consider the proximity effect between a singlet s-wave superconductor andthe edge of a Quantum Spin Hall QSH topological insulator. We establish thatAndreev reflection at a QSH edge state-superconductor interface is perfectwhile nonlocal Andreev processes through the superconductor are totallysuppressed. We compute the corresponding conductance and noise.
