Reducing the Quantumness of Composite Quantum Systems to Two Classical Compositions

Authors: Elemér E Rosinger
Comments: 20 pages.

A family of quantumness spaces is identified and precisely defined. They are spaces which characterize the difference between states given by classical compositions of systems, and on the other hand, states corresponding to their quantum compositions. Consequently, the quantum composition of systems is reduced to two classical compositions. A family of rankings is also defined for the respective family of quantumness.

Is Faster-Than-Light Communication Possible?

Authors: Raymond W. Jensen
Comments: 7 pages.

It is shown here using elementary quantum mechanics that a method exists for transmitting signals faster than the speed of light. The method relies on measurement of the uncertainty of momentum for one photon of each pair. The uncertainty is affected by whether momentum or position is measured for the partners, due to Heisenberg's uncertainty principle. For each pair the effect is instantaneous; so if the measurement of momentum uncertainty, done on one end, is distant from the momentum/position measurement switching done on the other end, then such behavior can be utilized for faster-than-light signaling.

A Prediction Loophole in Bell's Theorem

Authors: John R. Dixon
Comments: 5 pages.

We consider the Bell's Theorem setup of Gill et. al. (2002). We present a \proof of concept" that if the source emitting the particles can predict the settings of the detectors with sufficiently large probability, then there is a scenario consistent with local realism that violates the Bell inequality for the setup.

Deterministic Theory of the Tunnel Effect in the Esaki Junction

Authors: Daniele Sasso
Comments: 8 pages, 9 figures.

In scientific literature the Esaki junction is considered a typical system of quantum physics and its behavior is explained with the theory of probability. In this article we prove that the functioning of the Esaki junction can be explained very well without making use of the theory of probability but only by means of deterministic physical reasonings. This research is the first step in order to show that it is possible to think on a theory of quantum physics which is able to leave probability aside for a complete and exhaustive understanding of physical phenomena which happen in the microphysical world.

On the Measurement, Statistics and Uncertainty

Authors: Ibrahim Mutlay
Comments: 8 pages

It is intended here to propose descriptive explanations for the basic statistical concepts. Although most of them are highly familiar to us, their conventional descriptions have vague sides. Especially it was focused on the absolute probabilistic uncertainty which was characterized by momentum of the measurement device and the system which was measured.

What is the Matter with de Broglie Waves?

Authors: Constantinos Ragazas
Comments: 4 pages

The wave-particle duality of photons, as hypothesized by Einstein, was well accepted by the early 1920's. De Broglie's bold hypothesis in 1924, that all matter likewise has a wave-particle duality added further fuel to the fire in the development of Quantum Mechanics. It seared into the minds of physicists the wave-particle duality of Nature. Needless to say, this counter intuitive and bold assertion mystified the World beyond any sensible comprehension by common sense. The question often asked by ordinary people is "what is the matter with de Broglie waves?" We provide just this answer and demystify this 'matter' in this short paper.
