Google’s new quantum chip suggests multiple universes exist

On Monday, Google announced Willow, its newest, largest quantum computing chip. The speed and reliability performance claims Google made about the chip were newsworthy on their own, but what really caught the tech industry’s attention was an even wilder claim in a blog post about the chip.

Google Quantum AI creator Hartmut Neven wrote in his blog This chip is so insane that it must have taken its computing power from other universes.

Thus, the chip’s performance suggests that parallel universes exist and that “we live in a multiverse.”

Willow’s performance on this benchmark is astounding: In less than five minutes, it performed a calculation that would take one of today’s fastest supercomputers 1,025, or 10 septillion years. If you want to write it down, it’s 10,000,000,000,000,000,000,000,000 years. This astonishing number exceeds the time scale known in physics and greatly exceeds the age of the universe. This lends credence to the idea that quantum computing takes place in many parallel universes, a prediction first made by David Deutsch, consistent with the idea that we live in a multiverse.

It was the moment when he opened the microphone on the essence of reality was met with skepticism by some, but surprisingly others on the internet who claim to understand them He defended Neva’s conclusion was more convincing. Although the multiverse is a work of science fiction, it is also a serious field of study the founders of quantum physics.

However, skeptics point out that the performance claims are based on benchmarks that Google itself created a few years ago to measure quantum performance. That alone doesn’t prove that parallel versions of you aren’t wandering around in other universes – that’s where the main measuring stick came from.

Unlike classical digital computers, which calculate based on whether a bit is 0 or 1 (on or off), quantum computers are based on incredibly small qubits. They can be on/off or both (somewhere in between), and they can also tap into quantum entanglement—the mysterious connection between two or more particles at the smallest levels of the universe, where their states are bound regardless of the distance that separates them. .

Quantum computers use this kind of quantum mechanics to calculate extremely complex problems that cannot currently be solved by classical computers.

The problem is that the more qubits a computer uses, the more error-prone they become. So it’s not yet clear whether quantum computers will ever be reliable and powerful enough to live up to their hype. Google’s mission with Willow was to reduce these errors and Neven says that he succeeds.
