Quantum Entanglement and Information

Quantum Entanglement and Information
First published Mon Aug 13, 2001; substantive revision Thu Aug 26, 2010 Quantum entanglement is a physical resource, like energy, associated with the peculiar nonclassical correlations that are possible between separated quantum systems. Entanglement can be measured, transformed, and purified. A pair of quantum systems in an entangled state can be used as a quantum information channel to perform computational and cryptographic tasks that are impossible for classical systems. The general study of the information-processing capabilities of quantum systems is the subject of quantum information theory. 1. In 1935 and 1936, Schrödinger published a two-part article in the Proceedings of the Cambridge Philosophical Society in which he discussed and extended a remarkable argument by Einstein, Podolsky, and Rosen. It should not be supposed that Einstein's definition of a complete theory included the requirement that it be deterministic. He added (Schrödinger, 1935; p. 555): 2. 3. 4.

Bohmian Mechanics First published Fri Oct 26, 2001; substantive revision Mon Mar 4, 2013 Bohmian mechanics, which is also called the de Broglie-Bohm theory, the pilot-wave model, and the causal interpretation of quantum mechanics, is a version of quantum theory discovered by Louis de Broglie in 1927 and rediscovered by David Bohm in 1952. It is the simplest example of what is often called a hidden variables interpretation of quantum mechanics. Bohmian mechanics inherits and makes explicit the nonlocality implicit in the notion, common to just about all formulations and interpretations of quantum theory, of a wave function on the configuration space of a many-particle system. 1. Conceptual difficulties have plagued quantum mechanics since its inception, despite its extraordinary predictive successes. It might seem, since it is widely agreed that any quantum mechanical system is completely described by its wave function, that quantum mechanics is fundamentally about the behavior of wave functions. 2. 3.

Implicate and explicate order according to David Bohm Implicate order and explicate order are concepts coined by David Bohm to describe two different frameworks for understanding the same phenomenon or aspect of reality. He uses these notions to describe how the same phenomenon might look different, or might be characterized by different principle factors, in different contexts such as at different scales. The implicate order, also referred to as the "enfolded" order, is seen as a deeper and more fundamental order of reality. In contrast, the explicate or "unfolded" order include the abstractions that humans normally perceive. As he writes: In the enfolded [or implicate] order, space and time are no longer the dominant factors determining the relationships of dependence or independence of different elements. Overview[edit] The implicate order as an algebra[edit] I propose that each moment of time is a projection from the total implicate order. Bohm emphasized the primary role of the implicate order's structure:[4] Bohm went on to say:

Stanford Encyclopedia article Harald Atmanspacher haa@igpp.de It is widely accepted that consciousness or, more generally, mental activity is in some way correlated to the behavior of the material brain. Since quantum theory is the most fundamental theory of matter that is currently available, it is a legitimate question to ask whether quantum theory can help us to understand consciousness. Several approaches answering this question affirmatively, proposed in recent decades, will be surveyed. It will be pointed out that they make different epistemological assumptions, refer to different neurophysiological levels of description, and use quantum theory in different ways. 1. The problem of how mind and matter are related to each other has many facets, and it can be approached from many different starting points. As regards the issue of complexity, this is quite evident: the brain is one of the most complex systems we know. 2.

Relativity Tutorial Galilean Relativity Relativity can be described using space-time diagrams. Contrary to popular opinion, Einstein did not invent relativity. Galileo preceded him. Note the curved worldline above. Now it is still moving in its final state. Straight worldlines (unaccelerated particles) remain straight in this process. But Galilean transformations do not preserve velocity. Special Relativity But 200 years after Newton the theory of electromagnetism was developed into Maxwell's equations. Because the speed of light is special, space-time diagrams are often drawn in units of seconds and light-seconds, or years and light-years, so a unit slope [45 degree angle] corresponds to the speed of light. Thus in the situation shown in 3 space-time diagrams below, the central section shows the worldline of one stationary observer, one observer moving to the right, and two events on the future light cone on the event where the two observers' worldlines cross. However, this DOES NOT happen. Radar

Direct and indirect realism Direct realism argues we perceive the world directly History[edit] Aristotle was the first to provide a description of direct realism. In On the Soul he describes how a seer is informed of the object itself by way of the hylomorphic form carried over the intervening material continuum with which the eye is impressed.[5] Indirect realism was popular with early modern philosophers such as René Descartes and John Locke. Locke categorized qualities as follows: Primary qualities are qualities which are 'explanatorily basic' - which is to say, they can be referred to as the explanation for other qualities or phenomena without requiring explanation themselves - and they are distinct in that our sensory experience of them resembles them in reality. In contemporary philosophy, epistemological dualism has come under sustained attack by philosophers like Wittgenstein (the private language argument) and Wilfrid Sellars in his seminal essay "Empiricism and the Philosophy of Mind."

A Young People's Life of the Buddha In times long past, fully twenty-five hundred years ago, where are now the border-lands between Nepal and the northern parts of the provinces of Oudh and North Bihar, there were a number of little kingdoms inhabited by different races of people, each ruled over by its own Raja or King. One of these little kingdoms which lay some distance north of the present-day town of Gorakhpore, on the north side of the river Rapti, was the land of a race called the Sakyas, the king who ruled over them at that time being called Suddhodana. The family to which King Suddhodana of the Sakyas belonged was called the Gotama family, so that his full name was King Suddhodana Gotama; and the name of the chief city in his kingdom where he had his chief palace, was Kapilavatthu. This King Suddhodana had a chief queen whose name was Mahamaya. The place where this Lumbini Grove stood at that far off time can still be seen to-day. "Why!" "No, no, Maharaja," said the hermit, "do not be alarmed.
