Google revealed Willow, its newest and best quantum computer chip, on Monday. The tech world was interested in Google’s claims about the chip’s speed and dependability, but it was an even stranger claim tucked away in a blog post about the chip that really got people’s attention.
Hartmut Neven, the founder of Google Quantum AI, said in a blog post that this chip was so fast that it must have drawn computer power from other worlds.
So, the chip’s work shows that there are multiple universes and that “we live in a multiverse.”
This Is The Passage:
It’s amazing how well Willow did on this test: It did a calculation in less than five minutes that one of the fastest supercomputers in the world today would take 1025 years, or 10 septillion years. Ten billion years, if you want to write it down. This crazy number is much bigger than any known time scale in physics and much bigger than the age of the world. The idea that quantum computation happens in many parallel worlds is supported by this. This fits with the idea that we live in a multiverse, which was first proposed by David Deutsch.
Some people were skeptical of this “drop the mic” moment about the nature of reality, but surprisingly, people on the internet who say they understand these things said Nevan’s conclusions were more than believable. The founders of quantum physics are very interested in the universe, even though it’s mostly seen in science fiction.
But the doubters point out that the claims about speed are based on a standard that Google made years ago to measure quantum performance. That doesn’t prove that there aren’t parallel versions of you in other worlds; it just shows where the measuring stick came from.
Classic digital computers work by checking whether a bit is a 0 or 1 (on or off). Quantum computers, on the other hand, use very small qubits to do their work. These can be on/off or both (somewhere in the middle), and they can also use quantum entanglement, which is a strange link at the tiny levels of the universe between two or more particles that links their states together no matter how far apart they are.
Quantum computers use this kind of quantum physics to solve very hard problems that regular computers can’t handle right now.

What’s wrong is that computers make mistakes more often when they use more qubits. It’s still not clear if quantum computers will ever be strong and stable enough to live up to the hype. Google’s goal with Willow was to cut down on those mistakes, and Neven says it does that.
