Topological quantum interference
We experimentally observe topologically protected two-photon interference as a universal building block for the development of next-generation quantum circuits with built-in topological protection. We find propagation-invariant suppression of two-photon coincidences and robustness against perturbation as topological features in a laser-written waveguide coupler with tailored birefringence.
