Phys. Rev. A 57, 1583–1585 (1998)Strict bounds on the Franson inequalityReceived 31 July 1997; published in the issue dated March 1998 An inequality, recently proposed by Franson [Phys. Rev. A 54, 3808 (1996)], is analyzed and improved. The inequality connects the change of the expectation value of an observable with the uncertainty of this observable. A strict bound on the ratio between these two quantities is obtained. © 1998 The American Physical Society URL:
