Abstract
Colloidal quantum dots are efficient nanoscopic light emitters with interesting applications from optoelectronics to biomedical imaging. Their polarizability has now been measured directly by probing the electronic response without electrical contacts.

RESEARCH
The ability to coherently manipulate single electrons and photons is vital for quantum information processing. Experiments now demonstrate optical initialization, manipulation and probing of a single quantum dot on femtosecond timescales, revealing signatures of interaction effects, optical gain and the ability to change the number of quanta in a light pulse by one.
