Dynamics of transient cat-states in degenerate parametric oscillation with and without nonlinear Kerr interactions
R. Y. Teh, F. -X. Sun, R. E. S. Polkinghorne +4
A cat-state is formed as the steady-state solution for the signal mode of an ideal, degenerate parametric oscillator, in the limit of negligible single-photon signal loss. In the p…
Phase-space representations of thermal Bose-Einstein condensates
King Ng, Rodney Polkinghorne, Bogdan Opanchuk +1
Phase-space methods allow one to go beyond the mean-field approximation to simulate the quantum dynamics of interacting fields. Here, we obtain a technique for initializing either…
Quantum dynamics in ultra-cold atomic physics
Q. Y. He, M. D. Reid, B. Opanchuk +3
We review recent developments in the theory of quantum dynamics in ultra-cold atomic physics, including exact techniques, but focusing on methods based on phase-space mappings that…
Reply to Comment on ``Proposal for the Measurement of Bell-Type Correlations from Continuous Variables''
T. C. Ralph, W. J. Munro
Recently K. Banaszek, I. A. Walmsley, K. Wodkiewicz (quant-ph/0012097) commented on our Proposal for the Measurement of Bell-Type Correlations from Continuous Variables [T. C. Ralp…
Proposal for the Measurement of Bell-like Correlations from Continuous Variables
T. C. Ralph, W. J. Munro, R. E. S. Polkinghorne
We show theoretically that Bell-type correlations can be observed between continuous variable measurements performed on a parametric source. An auxiliary measurement, performed on…
Entanglement swapping using continuous variables
R. E. S. Polkinghorne, T. C. Ralph
We investigate the efficacy with which entanglement can be teleported using a continuous measurement scheme. We show that by using the correct gain for the classical channel the de…
Characterizing teleportation in optics
T. C. Ralph, R. E. S. Polkinghorne, P. K. Lam
We discuss the characterization of continuous variable, optical quantum teleportation in terms of the two quadrature signal transfer and conditional variances between the input and…
