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…
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…
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…
