Many of you will be familiar with the concept of parallel worlds, from science fiction or perhaps from Robert Anton Wilson's Schrödinger's Cat Trilogy.
Google put out an announcement this week on its new quantum computing chip, Willow. I've linked to it, including the discussion of Google's plans for a large scale quantum computer, but here is the bit catching everyone's attention, particularly the last sentence:
"Willow’s performance on this benchmark is astonishing: It performed a computation in under five minutes that would take one of today’s fastest supercomputers 1025 or 10 septillion years. If you want to write it out, it’s 10,000,000,000,000,000,000,000,000 years. This mind-boggling number exceeds known timescales in physics and vastly exceeds the age of the universe. It lends credence to the notion that quantum computation occurs in many parallel universes, in line with the idea that we live in a multiverse, a prediction first made by David Deutsch."
