Tradeoffs for number-squeezing in collisions of Bose-Einstein condensates
P. Deuar, T. Wasak, P. Zin +2
We investigate the factors that influence the usefulness of supersonic collisions of Bose-Einstein condensates as a potential source of entangled atomic pairs by analyzing the redu…
Bogoliubov dynamics of condensate collisions using the positive-P representation
P. Deuar, J. Chwedenczuk, M. Trippenbach +1
We formulate the time-dependent Bogoliubov dynamics of colliding Bose-Einstein condensates in terms of a positive-P representation of the Bogoliubov field. We obtain stochastic evo…
Non-local pair correlations in the 1D Bose gas at finite temperature
P. Deuar, A. G. Sykes, D. M. Gangardt +3
The behavior of the spatial two-particle correlation function is surveyed in detail for a uniform 1D Bose gas with repulsive contact interactions at finite temperatures. Both long-…
Quantum dynamics in phase space: From coherent states to the Gaussian representation
P. D. Drummond, P. Deuar, T. G. Vaughan +1
We give an outlook on the future of coherence theory and many-body quantum dynamics as experiments develop in the arena of ultra-cold atoms. Novel results on quantum heating of cen…
Quantum copying can increase the practically available information
P. Deuar, W. J. Munro
While it is known that copying a quantum system does not increase the amount of information obtainable about the originals, it may increase the amount available in practice, when o…
Qudit Entanglement
P. Rungta, W. J. Munro, K. Nemoto +3
We consider the separability of various joint states of D-dimensional quantum systems, which we call "qudits." We derive two main results: (i) the separability condition for a two-…
