A quantum computer that can calculate . . . while it’s not running.

“It is very bizarre that you know your computer has not run but you also know what the answer is,” says [University of Illinois at Urbana-Champaign research] team member Onur Hosten.

“Very bizarre.” Master of the understatement, Onur.

This scheme could have an advantage over straightforward quantum computing. “A non-running computer produces fewer errors,” says Hosten.

Let me guess: Microsoft operating system!
