The Nobel Prize in Physics was on Tuesday awarded to three U.S.-based scientists for their discoveries in quantum mechanics.

A trio of professors in the US won the Nobel prize in physics for their work on the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.

Quantum effects were known at the level of atoms, but in the 1980s John Clarke, Michel H. Devoret, and John M. Martinis showed that at very low temperatures, the strange behavior — such as particles ...
