A novel delayed-choice experimental proposal testing local decisions

چکیده
Entangled states are notoriously non-separable, their sub-ensembles being only statistical mixtures yielding no coherences and no quantum interference phenomena. The interesting features of entangled states can be revealed only by coincidence counts over the (typically) two sub-ensembles of the system. In this paper we show that this feature extends to properties thought to be local, for example the transmissivity coefficient of a beam splitter. We discuss a well-known experimental setup and propose modifications, so that delayed-choice can be added and this new feature of entanglement tested. PACS.

Impulsive responding in alcoholics.
BACKGROUND Impaired decision-making is one diagnostic characteristic of alcoholism. Quantifying decision-making with rapid and robust laboratory-based measures is thus desirable for the testing of novel treatments for alcoholism. Previous research has demonstrated the utility of delay discounting (DD) tasks for quantifying differences in decision-making in substance abusers and normal controls....

Offering reliable novel service in modern heterogeneous networks is a key challenge and an important prospective income source for many network operators and providers. Providing reliable future service in a cost effective scalable manner requires efficient use of networking and computing resources. This can be done by making the network more self enabled, i.e. making it capable of making distr...
متن کاملThe confidence-accuracy relationship for eyewitness identification decisions: Effects of exposure duration, retention interval, and divided attention.
Prior research points to a meaningful confidence-accuracy (CA) relationship for positive identification decisions. However, there are theoretical grounds for expecting that different aspects of the CA relationship (calibration, resolution, and over/underconfidence) might be undermined in some circumstances. This research investigated whether the CA relationship for eyewitness identification dec...
