Some Fundamental Experiments

Fundamentally binary theories are nonsignaling theories in which measurements of many outcomes are constructed by selecting from binary measurements. They constitute a sensible alternative to quantum theory and have never been directly falsified by any experiment. Here we show that fundamentally binary theories are experimentally testable with current technology. For that, we identify a feasible Bell-type experiment on pairs of entangled qutrits. In addition, we prove that, for any $n$, quantum $n$-ary correlations are not fundamentally $(n\ensuremath{-}1)$-ary. For that, we introduce a family of inequalities that hold for fundamentally $(n\ensuremath{-}1)$-ary theories but are violated by quantum $n$-ary correlations.

Its effects or the result of a random experiment is any fundamental physics of a phenomenon called. Experience consists of all the fundamental forces of physics phenomena that can happen as a result of the package of the fundamental forces of physics phenomena space or the package space, and we are called through the understanding of the character, while each is a phenomenon of physics fundamental understanding of the character through

With the coming of quantum information and associated technologies, there is increasing need to prepare students on the fundamentals of quantum physics. Fundamental physical principles can be hidden by the mathematical formalism of quantum mechanics. Thus it is necessary to expose students to experiments that illustrate fundamentals. Quantum optics experiments based on the generation of twin photons via spontaneous parametric down-conversion have many advantages, such as being simple, reliable, and of reasonable cost. These types of experiments are ideal for the advanced laboratory in the physics curriculum. At Colgate University we offer them as a laboratory package that is associated with our upper-level undergraduate course on quantum mechanics. In this article we present our latest approaches. Among them is a new layout for the experiments to provide a more intuitive physical picture.
