The quantum-mechanical "Schrödinger's cat" paradox according to the many-worlds interpretation.In this interpretation, every quantum event is a branch point; the cat is both alive and dead, even before the box is opened, but the "alive" and "dead" cats are in different branches of the multiverse, both of which are equally real, but which do not interact with each other.
The definition of quantum theorists' terms, such as wave function and matrix mechanics, progressed through many stages.For instance, Erwin Schrödinger originally viewed the electron's wave function as its charge density smeared across space, but Max Born reinterpreted the absolute square value of the wave function as the electron's probability density distributed across space; [3]: 24–33 ...
The quantum-mechanical "Schrödinger's cat" paradox according to the many-worlds interpretation. In this interpretation, every event is a branch point. The cat is both alive and dead—regardless of whether the box is opened—but the "alive" and "dead" cats are in different branches of the universe that are equally real but cannot interact ...

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 ...
Mermin, Mayer and Baez noted that Peres briefly dismissed the many-worlds interpretation of quantum mechanics. [ 4 ] [ 10 ] [ 14 ] Peres argued that all varieties of many-worlds interpretations merely shifted the arbitrariness or vagueness of the wavefunction collapse idea to the question of when "worlds" can be regarded as separate, and that ...
The Many-worlds interpretation, also known as the Everett interpretation, is dynamically local, meaning that it does not call for action at a distance, [77]: 17 and deterministic, because it consists of the unitary part of quantum mechanics without collapse. It can generate correlations that violate a Bell inequality because it violates an ...
Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot.
