Bell non-locality between distant quantum systems--that is, joint correlations which violate a Bell inequality--can be verified without trusting the measurement devices used, nor those performing the measurements. This leads to unconditionally secure protocols for quantum information tasks such as cryptographic key distribution. However, complete verification of Bell non-locality requires high ...

A Bell inequality defined for a specific experimental configuration can always be extended to a situation involving more observers, measurement settings, or measurement outcomes. In this article, such “liftings” of Bell inequalities are studied. It is shown that if the original inequality defines a facet of the polytope of local joint outcome probabilities then the lifted one also defines a fac...

A memorial conference for John Bell, open to the public, was held at Rutgers University around 20 years ago. I gave there a short talk on Bell’s views about David Bohm’s “hidden variables” formulation of quantum mechanics, a version of quantum mechanics often called the de Broglie-Bohm theory or Bohmian mechanics. This theory was in fact discovered by Louis de Broglie in 1927. In 1952, it was r...

We investigate the steerability of two-qubit Bell-diagonal states under projective measurements by the steering party. In the simplest nontrivial scenario of two projective measurements, we solve this problem completely by virtue of the connection between the steering problem and the joint-measurement problem. A necessary and sufficient criterion is derived together with a simple geometrical in...

Bell peppers grown in greenhouses in the Mediterranean region are frequently subjected to high temperatures in summer and low temperatures in winter. The present experiment was designed to quantify the effect of season on pepper fruit growth, maturation and ripening. Three bell pepper (Capsicum annuum L.) cultivars (Yolo Wonder, California Wonder and E84066) were cultivated in an unheated ...

The theorem of Bell states that certain results of quantum mechanics violate inequalities that are valid for objective local random variables. We show that the inequalities of Bell are special cases of theorems found ten years earlier by Bass and stated in full generality by Vorob’ev. This fact implies precise necessary and sufficient mathematical conditions for the validity of the Bell inequal...

Nanotechnology is an emerging discipline, having power to revolutionarize every scientific field to a very deep level which previously thought to be a science fiction. Having a great potential to beneficially change the way a disease is diagnosed, treated and prevented, nanotechnology practically impacts on state of the art healthcare technologies and plays a crucial role in changing the field ...

(Bell Labs) during the 20-some years following Bell Labs' entry into the digital computer era. In doing so, I describe various problems that Bell Labs was addressing and characteristics of the machines developed as solutions. During this period, Bell Labs was AT&T's research and development arm, and Western Electric was AT&T's manufacturing division. Western Electric and AT&T each owned 50 perc...

The paper presents a method for automatic transcription of recordings of bell chiming performances. Bell chiming is a Slovenian folk music tradition involving performers playing tunes on church bells by holding the clapper and striking the rim of a stationary bell. The tunes played consist of repeated rhythmic patterns into which various changes are included. Because the sounds of bells are inh...
