If there’s one thing you can be sure of here at Physics World, it’s that any coverage of “time crystals” gets lapped up by readers.
With that in mind, the cover feature of the new April 2022 issue of Physics World magazine, is sure to intrigue you.
Written by Pedram Roshan from Google’s AI quantum team in California, the article describes this elusive form of matter and how it could be simulated on the company’s Sycamore quantum processor.
You can also read the article on the website from Monday 4 April 2022.
