Phys. Rev. A 67, 032108 (2003) [6 pages]Complementarity and duality relations for finite-dimensional systemsReceived 7 December 2002; published 19 March 2003 We generalize to systems with arbitrary finite dimension a measure of quantum fluctuations (the certainty) previously introduced for two-dimensional systems. Using this measure, we study the duality relations satisfied by complementary observables looking for states with minimum joint fluctuations (maximum certainty states). We extend the duality relations to encompass several complementary observables simultaneously. © 2003 The American Physical Society URL:
