Abstract : The International Workshop on Coherent Control of Charge Carrier Dynamics in Semiconductors was held May 18-22,1998 at the University of Illinois at Chicago. An international and multi-disciplinary group of scientists presented recent results on coherent control phenomena in atoms, molecules, and semiconductors. Pertinent open physical questions, as well as potential technological applications and the future of the field were discussed. Referred proceedings were published under the title Coherent Control in Atoms, Molecules, and Semiconductors, by Kluwer in spring of 1999 (ISPN 0-7923-5649-7)

We describe a coherent control technique for coupling electron spin states associated with semiconductor double-dot molecule to a microwave stripline resonator on a chip. We identify a novel regime of operation in which strong interaction between a molecule and a resonator can be achieved with minimal decoherence, reaching the so-called strong coupling regime of cavity QED. We describe potential applications of such a system, including low-noise coherent electrical control, fast QND measurements of spin states, and long-range spin coupling.
