The 2025 Nobel Prize in Physics Explained, with John Martinis
Tunneling Time is Not Instantaneous: Contrary to common belief, quantum tunneling takes a finite amount of time (the 'tunneling traversal time'). This delay is influenced by the distance to resistors and the speed of ligtakeaway“By the time you get up to 53 cubits, that's 10^ the 16 states in parallel. And by the time you get to, you know, hundreds, that's a number bigger than there are atoms in the universe. You can become God.”quote“It takes some time for it to tunnel... if the resistor is far away, it tunnels before it can... see the the delay there. It's a the speed of light delay between the junction and the resistor.”quote
