Multiverse Of Messiness

Welcome to the multiverse:

Calling Willow’s performance ‘astonishing,’ the leader and founder of Google Quantum AI team, physicist Hartmut Neven, said its high-speed result ‘lends credence to the notion that quantum computation occurs in many parallel universes.’ Neven credited Oxford University physicist David Deutsch for proposing the theory that the successful development of quantum computing would, in effect, affirm the ‘many worlds interpretation’ of quantum mechanics and the existence of a multiverse. Starting in the 1970s, Deutsch, in fact, had walked backward into becoming a pioneer in the field of quantum computing, less out of interest in the technology itself than his desire to test the multiverse theory. Astrophysicist turned science writer Ethan Siegel blasted Google over the claim, accusing them of ‘conflating unrelated concepts, which Neven also ought to know.’ ‘Neven has conflated the notion of a quantum mechanical Hilbert space, which is an infinite-dimensional mathematical space where quantum mechanical wavefunctions “live,” with the notion of parallel universes and a multiverse,’ Siegel argued Friday.

So that explains where all those other versions of me came from...
