In quantum mechanics, quantum suicide is a thought experiment, originally published independently by Hans Moravec in 1987[1][2] and Bruno Marchal in 1988[3][4] and independently developed further by Max Tegmark in 1998.[5] It attempts to distinguish between the Copenhagen interpretation of quantum mechanics and the Everett many-worlds interpretation by means of a variation of the Schrödinger's cat thought experiment, from the cat's point of view. Quantum immortality refers to the subjective experience of surviving quantum suicide regardless of the odds.[6]
