| + | Ognyan Oreshkov from QuIC and colleagues Jonathan Barrett and Robin Lorenz from the University of Oxford have developed a theory of causality in quantum theory, according to which cause-effect relations can sometimes form cycles. This theory offers a novel understanding of exotic processes in which events do not have a definite causal order. The study has been published in [[https://www.nature.com/articles/s41467-020-20456-x|Nature Communications]]. | ||
