Google says it accessed parallel universes with its new supercomputer
Briefly

Physicist Hartmut Neven called Willow's performance 'astonishing,' stating that the speed of solving the complex problem 'lends credence to the notion that quantum computation occurs in many parallel universes.' This reflects a major breakthrough in believing the multiverse theory based on quantum computing achievements.
Astrophysicist Ethan Siegel criticized Google's claims, arguing that 'Neven has conflated the notion of a quantum mechanical Hilbert space...with the notion of parallel universes and a multiverse.' He emphasizes that such physics interpretations are unrelated to quantum computing's success.
