In a quantum race, everyone is both a winner and a loser

Our understanding of the world is mostly built on basic perceptions, such as that events follow each other in a well-defined order. Such definite orders are required in the macroscopic world, for which the laws of classical physics apply. However, in the quantum world orders can be ‘scrambled’. It is possible for different orders of quantum operations to coexist in a superposition. New work by a team of physicists is the first experimental quantification of such a superposition.
