Abstract: Highly detuned interactions appear in many instances in quantum optics, such as A.C. Stark shifts and Raman transitions. Here I discuss a formalism to describe such interactions in systematic way, by deriving an effective hamiltonian
Abstract: This talk deals with the issue of speed in quantum computing: despite its successes in creating large-scale entanglement and demonstrating simple algorithms, and their promise of scalability, current trapped ion devices are too slow to be competitive with conventional technologies. Possible ways around this are discussed.
Abstract: In this talk I discussed the current state of the art in experimental realization of quantum computing in General (and in trapped ion in particular) and discussed some of the problems facing near and long term developments and how they might be resolved. (Similar talks were given at Los Alamos and UNM, Jul 06; a CIAR meeting at Toronto and at IQOQI, Innsbruck in Jan 07).
Abstract: Nearly 15 years after it was originally proposed, Shor's factoring algorithm remains the most important potential application for quantum computers. In this talk, I will give a gentle introduction to how the algorithm works, and describe a recent experiment carried out using linear optics quantum computing.
Abstract: This talk will present an intuitive explanation of the promise of a new generation of proposed technologies intended to exploit fundamentally quantum mechanical phenomena in order to perform tasks such as communication, metrology and computation in a dramatically more efficient manner than conventional devices in use today. We will also discuss the physical principles behind the devices and the latest progress toward realizing some of these ambitious goals.
Abstract: I will give an introductory overview of current experimental techniques used to characterize the density matrix of a system and the quantum process describing a device, with emphasis on applications in quantum optics.
