Quantum violation of an instrumental test published in Nature Physics!

Theory and experiment show that quantum correlations violate the instrumental test – a common statistical method used to estimate the strength of causal relationships between two variables. Our last collaboration with Rafael Chaves and Leandro Aolita just published in Nature Physics!
