Three scientists awarded the 2025 Physics Nobel for developing device that demonstrates quantum tunneling

The Physics Nobel 2025 has been awarded this year to three scientists whose experiments provided greater insight into the strange quantum world. The Royal Swedish Academy of Sciences said: “T he three Nobel Prize winners 2025, John Clarke, Michel Devoret and John Martinis, have opened the door to the world of the ultra-small, where individual particles can act in ways that contradict classical physics and common sense.” One of the Nobel Prize in Physics effects is “tunnelling”, which essentially means that the particles are able to pass through barriers that stop other objects in their path. To offer a comparison, it’s as if a cricket ball that has been bowled hits the pitch and, instead of bouncing up as expected, it tunnellers straight into the ground. The three scientists showed tha
