Wigner's friends, tunnelling times and Feynman's "only mystery of quantum mechanics"

Abstract

Recent developments in elementary quantum mechanics have seen a number of extraordinary claims regarding quantum behaviour, and even questioning internal consistency of the theory. These are, we argue, different disguises of what Feynman described as quantum theory's "only mystery".
