Angular minimum uncertainty states with large uncertainties
Joerg B. Goette, Paul M. Radmore, Roberta Zambrini +1
The uncertainty relation for angle and angular momentum has a lower bound which depends on the form of the state. Surprisingly, this lower bound can be very large. We derive the st…
Light induced effective magnetic fields for ultra-cold atoms in planar geometries
G. Juzeliunas, J. Ruseckas, P. Ohberg +1
We propose a scheme to create an effective magnetic field for ultra-cold atoms in a planar geometry. The set-up allows the experimental study of classical and quantum Hall effects…
Effective magnetic fields induced by EIT in ultra-cold atomic gases
G. Juzeliunas, J. Ruseckas, P. Ohberg
We study the influence of two resonant laser beams (to be referred to as the control and probe beams) on the centre of mass motion of ultra-cold atoms characterised by three energy…
Joint measurements of spin, operational locality and uncertainty
Erika Andersson, Stephen M. Barnett, Alain Aspect
Joint, or simultaneous, measurements of non-commuting observables are possible within quantum mechanics, if one accepts an increase in the variances of the jointly measured observa…
Joint measurements and Bell inequalities
Wonmin Son, Erika Andersson, Stephem M. Barnett +1
Joint quantum measurements of non-commuting observables are possible, if one accepts an increase in the measured variances. A necessary condition for a joint measurement to be poss…
Quantum nature of laser light
David T. Pegg, John Jeffers
All compositions of a mixed-state density operator are equivalent for the prediction of the probabilities of future outcomes of measurements. For retrodiction, however, this is not…
Angular EPR paradox
Joerg B Goette, Sonja Franke-Arnold, Stephen M. Barnett
The violation of local uncertainty relations is a valuable tool for detecting entanglement, especially in multi-dimensional systems. The orbital angular momentum of light provides…
Large-uncertainty intelligent states for angular momentum and angle
Joerg B. Goette, Roberta Zambrini, Sonja Franke-Arnold +1
The equality in the uncertainty principle for linear momentum and position is obtained for states which also minimize the uncertainty product. However, in the uncertainty relation…
Resolution in rotation measurements
Stephen M Barnett, Roberta Zambrini
The limiting resolution in optical interferometry is set by the number of photons used, with the functional dependence determined by the state of light that is prepared. We conside…
Cavity state preparation using adiabatic transfer
Jonas Larson, Erika Andersson
We show how to prepare a variety of cavity field states for multiple cavities. The state preparation technique used is related to the method of stimulated adiabatic Raman passage o…
