Cooling many particles to very low temperatures
Almut Beige, Peter L. Knight, Giuseppe Vitiello
In a recent paper [Beige, Knight, and Vitiello, quant-ph/0404160], we showed that a large number N of particles can be cooled very efficiently using a bichromatic interaction. The…
Speeding up gate operations through dissipation
Almut Beige, Hugo Cable, Carsten Marr +1
It is commonly believed that decoherence is the main obstacle to quantum information processing. In contrast to this, we show how decoherence in the form of dissipation can improve…
Quantum gates and decoherence
Stefan Scheel, Jiannis Pachos, E. A. Hinds +1
In the lectures we will be concerned with some aspects of physical implementations of quantum gate operations which are necessary for quantum information processing. We will discus…
Post-processing with linear optics for improving the quality of single-photon sources
Dominic W. Berry, Stefan Scheel, Casey R. Myers +3
Triggered single-photon sources produce the vacuum state with non-negligible probability, but produce a much smaller multiphoton component. It is therefore reasonable to approximat…
On improving single photon sources via linear optics and photodetection
Dominic W. Berry, Stefan Scheel, Barry C. Sanders +1
In practice, single photons are generated as a mixture of vacuum with a single photon with weights 1-p and p, respectively; here we are concerned with increasing p by directing mul…
Quantum state restoration by quantum cloning and measurement
K. Maruyama, P. L. Knight
Copying information is an elementary operation in classical information processing. However, copying seems rather different in the quantum regime. Since the discovery of the univer…
