15 صفحه اولThe Curious Quantum Mechanics of Pre- and Post-Selected Ensembles
In a provocative paper, (~) Albert, Aharonov, and D'Amato proposed an analysis of preand post-selected ensembles in quantum mechanics (PPS ensembles) which seemed to show that in the interval between preand post-selection, certain noncommuting observables all have determinate values. Moreover, these values are context dependent: The value assumed by a degenerate observable (e.g., an observable ...
متن کاملNonperturbative theory of weak pre- and post-selected measurements
This paper starts with a brief review of the topic of strong and weak preand post-selected (PPS) quantum measurements, as well as weak values, and afterwards presents original work. In particular, we develop a nonperturbative theory of weak PPS measurements of an arbitrary system with an arbitrary meter, for arbitrary initial states of the system and the meter. New and simple analytical formula...
متن کاملInteraction with a pre and post selected environment and recoherence
The interaction of an open system S with a preand post-selected environment is studied. In general, under such circumstances S can not be described in terms of a density matrix, even when S in not post-selected. However, a simple description in terms of a two-state (TS) is always available. The two-state of S evolves in ti me from an initially ‘pure’ TS to a ‘mixed’ TS and back to a final ‘pure...
متن کاملSecure Key Distribution via Pre- and Post-Selected Quantum Ensembles
A quantum key distribution scheme whose security depends on the features of preand post-selected quantum ensembles is described. PACS numbers: 03.65.Bz, 42.80.Sa, 89.70.+c A wide variety of quantum key distribution schemes have been proposed, following the original Bennett and Brassard protocol [1]. Ekert [2] has described a scheme in which two parties, Alice and Bob, create a shared random key...
