In 1985, David Deutsch proposed a variant of the Wigner's friend thought experiment as a test of many-worlds versus the Copenhagen interpretation. [32] It consists of an experimenter (Wigner's friend) making a measurement on a quantum system in an isolated laboratory, and another experimenter (Wigner) who would make a measurement on the first one.
After supporting Everett's work for several years, he began to distance himself from the many-worlds interpretation in the 1970s. [95] [96] Late in life, he wrote that while the Copenhagen interpretation might fairly be called "the fog from the north", it "remains the best interpretation of the quantum that we have". [97]
The main conclusion of the authors is that "the Copenhagen interpretation still reigns supreme", receiving the most votes in their poll (42%), besides the rise to mainstream notability of the many-worlds interpretations: "The Copenhagen interpretation still reigns supreme here, especially if we lump it together with intellectual offsprings such ...
In both polls, the Copenhagen interpretation received the largest number of votes. In Tegmark's poll, many-worlds interpretations came in second place, while in the 2011 poll, many-worlds was at third place (18%), behind quantum information approaches in second place (24%).
An alternative interpretation, the Many-worlds Interpretation, was first described by Hugh Everett in 1957 [3] [4] (where it was called the relative state interpretation, the name Many-worlds was coined by Bryce Seligman DeWitt starting in the 1960s and finalized in the 1970s [5]). His formalism of quantum mechanics denied that a measurement ...
