  Controlling topological phases of light has allowed experimental observations
of abundant topological phenomena and development of robust photonic devices.
The prospect of more sophisticated controls with topological photonic devices
for practical implementations requires high-level programmability. Here, we
demonstrate a fully programmable topological photonic chip with large-scale
integration of silicon photonic nanocircuits and microresonators. Photonic
artificial atoms and their interactions in our compound system can be
individually addressed and controlled, therefore allowing arbitrary altering of
structural parameters and geometrical configurations for the observations of
dynamic topological phase transitions and diverse photonic topological
insulators. By individually programming artificial atoms on the generic chip,
it has allowed comprehensive statistic characterisations of topological
robustness against relatively weak disorders, as well as counterintuitive
topological Anderson phase transitions induced by strong disorders. Our generic
topological photonic chip that can be rapidly reprogrammed to implement
multifunctionalities, prototypes a flexible and versatile platform for possible
applications across fundamental science and topological technologies.
