Control at the Quantum Level

by Thomas F. Krauss Science, 20 May 2005 Controlling the interaction between an emitter and an optical cavity resonator in the solid state is of great interest for quantum devices, such as single-photon emitters and, eventually, quantum computers. In his Perspective, Krauss highlights the report of Badolato et al., who achieve much greater control than hitherto possible in a quantum dot-photonic crystal nanocavity system. Krauss concludes that this work is a significant step toward producing practical devices. Read the article
