John Clarke, Michel Devoret and John Martinis honoured for their observations of quantum effects in a superconducting electric circuit

Three California-based scientists have been awarded the Nobel prize in physics for their observations of quantum mechanical tunnelling on the macroscopic scale. The discovery by John ClarkeMichel Devoret and John Martinis provided some of the fundamental insights on which modern quantum engineering and efforts to build quantum computers rely.
