We present a set of Bell inequalities which are sufficient and necessary for separability of general pure multipartite quantum states in arbitrary dimensions. The relations between Bell inequalities and distillability are also studied. We show that any quantum states that violate one of these Bell inequalities are distillable.

We develop an extension of the classical Bell polynomials introducing the Laguerre-type version of this well-known mathematical tool. The Laguerre-type Bell polynomials are useful in order to compute the nth Laguerre-type derivatives of a composite function. Incidentally, we generalize a result considered by L. Carlitz in order to obtain explicit relationships between Bessel functions and gener...

It is explained on a physical basis how absence of contextuality allows Bell inequalities to be violated, without bringing an implication on locality or realism. The point is that the initial values of the hidden variables of the detectors are mutually exclusive for different detector settings. Therefore they have no reason to possess a common probability distribution and hence no reason to sat...

We describe possible kaon physics goals to achieve with a high luminosity Φ−factory. We motivate the relevance to improve the present bounds on CPT kaon physics quantities. Also, the interferometer machine Φ−factory is useful to study CP violating/conserving effects in kaon decays. Thus we investigate K → 3π amplitudes: charge asymmetries are interesting in charged kaon decays. In the case of n...

It is known that it is impossible to unambiguously distinguish the four Bell states encoded in pairs of photon polarizations using only linear optics. However, hyperentanglement, the simultaneous entanglement in more than one degree of freedom, has been shown to assist the complete Bell analysis of the four Bell states given a fixed state of the other degrees of freedom . Yet introducing other ...

E very illness is a story, and Annie Page’s began with the kinds of small, unexceptional details that mean nothing until seen in hindsight. Like the fact that, when she was a baby, her father sometimes called her Little Potato Chip, because her skin tasted salty when he kissed her. Or that Annie’s mother noticed that her breathing was sometimes a little wheezy, though the pediatrician heard not...

The assumptions underlying security policy models, such as the Bell-LaPadula model, are usually not explicitly stated. This has led to several common misconceptions about this model and its scope. A comparison of manual and automated systems is used to demonstrate the derivation of the Bell-LaPadula ?property (pronounced star-property) for automated systems and its analog for manual systems. Th...

BACKGROUND Recovery of Bell`s phenomenon after levator resection is unpredicatable. Delayed recovery can result in vision threatening corneal complications. AIM To study the variability of Bell's phenomenon and time taken for its recovery following levator resection for blepharoptosis and to correlate it with the amount of resection. METHODS A prospective observational study was conducted o...

Obtaining accurate kinematic data of animals is essential for many biological studies and bio-inspired engineering. Many animals, however, are either too large or too delicate to transport to controlled environments where accurate kinematic data can be easily obtained. Often, in situ recordings are the only means available but are often subject to multi-axis motion and relative magnification ch...
