We prove that circuit complexity satisfies all requirements for physical observables, including self-adjointness, gauge invariance, and a consistent measurement theory with well-defined uncertainty ...

"This feels like we have our finger right on the knob of quantum mechanics," Feldman said. "It's an aspect of quantum mechanics that we didn't know about or, at least, we didn't appreciate before ...

Did these researchers truly just crack our fundamental concepts of (quantum) physics wide open? As it turns out, not really. Much of the confusion stems from the fact that photons aren’t little ...
