We might imagine that electric current flows as a smooth, even stream of electrons through our electronics devices, but at the quantum scale the flow of electric current might be more accurately pictured as a bubbling brook ...
(Phys.org)—As the saying goes, no two fingerprints are alike, and the same is true for quantum fingerprints. Just as a human fingerprint is only a fraction of the size of a person, yet can be used to distinguish between ...
(Phys.org) —If you're in the business of cracking codes, it would be pretty difficult to break into a security system that you don't even know is there. That's one of the advantages of molecular keypad locks, whose small ...
