Passing through walls… Broken glass…
Researchers have captured the most direct evidence to date of Klein tunneling, a quantum quirk that allows particles to tunnel through a barrier like it’s not even there. The result may enable engineers to design more uniform components for future quantum computers, quantum sensors and other devices. (1) We constantly see things. We sense things.…
