$Alphabet(GOOG)$ Google's new quantum chip, Willow, pulled off something that almost doesn't sound real. It finished a calculation in under five minutes that would take the fastest classical supercomputers roughly 10 septillion years. That's not just longer than recorded human history — it's longer than the age of the universe by such a ridiculous margin that the number starts to feel abstract.

On the surface it looks like a pure computing breakthrough. But underneath the headline there's a weirder question: where did that computational power actually come from? Some physicists think quantum computers aren't just crunching numbers inside our universe. They may be processing possibilities across many branches of reality at the same time. If that interpretation is even partly right, Willow might not just be a faster chip. It could be the first real technology that forces us to confront whether parallel universes are part of how computation itself works, not just science fiction.
