Random numbers are an important resource for applications such as numerical
simulation and secure communication. However, it is difficult to certify whether a physical
random number generator is truly unpredictable. Here, we exploit the phenomenon of quantum
nonlocality in a loophole-free photonic Bell test experiment for the generation of randomness
that cannot be predicted within any physical theory that allows one to make independent
measurement choices and prohibits superluminal signaling. To certify and quantify the
randomness, we describe a new protocol that performs well in an experimental regime
characterized by low violation of Bell inequalities. Applying an extractor function to our
data, we obtained 256 new random bits, uniform to within 0.001. arXiv:1702.05178
