Laser spectroscopy is a technique of immense value in atom optics as recognised with last year’s Nobel Prize for Physics. Can it be applied to an artificial atom in the solid state, a quantum dot? In order to remove the inhomogeneous broadening it is essential to attempt these experiments on just a single quantum dot, a challenging enterprise. We have now succeeded in this mission. The talk presents laser spectroscopy on a single quantum dot presenting the detection scheme, an exchange interaction which we can turn on and off simply with a bias voltage, and the effects of both electron and hole tunneling.
