New quantum paradox clarifies where our views of reality go wrong (2018)


The Frauchiger-Renner thought experiment has shaken up the world of quantum foundations.

The experiment, designed by Daniela Frauchiger and Renato Renner, of the Swiss Federal Institute of Technology Zurich, involves a set of assumptions that on the face of it seem entirely reasonable. “I have to admit that if you had asked me two years ago, I’d have said [our experiment] just shows that many-worlds is actually a good interpretation and you should give up” the requirement that measurements have only a single outcome, Renner said. The effort to explicate how various interpretations of quantum theory violate the assumptions has been “an extremely useful exercise,” said Rob Spekkens of the Perimeter Institute for Theoretical Physics in Waterloo, Canada.
