Computer networks are the foundation of our digital economy. Quantum computing offer revolutionary solutions to current limitations by taking advantage of quantum physics. Methods for factoring large numbers or searching unordered databases run with significantly fewer operations on quantum computers. Quantum encryption offers completely secure communication. There have been small-scale demonstrations of these technologies, and clear roadmaps exist for large-scale implementations. We will advance the state of the art by interconnecting light based quantum communication and trapped ion quantum computing together with phase Fresnel lenses, a micro-fabricated optic similar to a computer generated holographic plate.Read moreRead less

Generation and Application of Ultracold Molecules. This project will extend the techniques of laser trapping and cooling of neutral atoms to produce ensembles of ultracold molecules, specifically Rb2. The starting point will be a cold sample of atoms, followed by the photoassociative formation of ultracold molecules. The ultracold molecules will be collected in a far-detuned optical dipole trap, and subsequently probed using femtosecond time-resolved spectroscopy. This unique combination of femt ....Generation and Application of Ultracold Molecules.

The starting point will be a cold sample of atoms, followed by the photoassociative formation of ultracold molecules. The ultracold molecules will be collected in a far-detuned optical dipole trap, and subsequently probed using femtosecond time-resolved spectroscopy. This unique combination of femtosecond spectroscopy with ultraslow molecules will extend the study of chemical processes to an entirely new temperature regime, leading to a new understanding of the quantum nature of chemical reactions.Read moreRead less

Researchers are now able to produce and

This project extends work in this field to the investigation of physics at the quantum/classical boundary through the study of the dynamics of BECs on atom chips. By probing a nonlinear system with a BEC we will examine how the quantum mechanics affects classically chaotic dynamics. We will also examine the classically forbidden phenomena of dynamical tunnelling and localisation.Read moreRead less
