Query: Nonlocality from local contextuality   We experimentally show that nonlocality can be produced from single-particle
contextuality by using two-particle correlations which do not violate any Bell
inequality by themselves. This demonstrates that nonlocality can come from an
{\em a priori} different simpler phenomenon, and connects contextuality and
nonlocality, the two critical resources for, respectively, quantum computation
and secure communication. From the perspective of quantum information, our
experiment constitutes a proof of principle that quantum systems can be used
simultaneously for both quantum computation and secure communication.
