2012 Nobel Prize in Physics and the coherent control of single quantum systems

Gerard Milburn

Serge Haroche and David Wineland shared the 2012 Nobel Prize in Physics for pioneering the coherent control of single quantum systems. Haroche’s work used photons in a single superconducting microwave cavity; Wineland’s  used one or more single trapped ions. Their work laid the foundations for a nascent quantum technology and provided experimental answers to foundational questions such as quantum measurement and decoherence. In this talk I will describe the science behind their key experiments and look forward to a future quantum technology based on coherent quantum control.
