Quantum theory reveals puzzling pattern in how people respond to some surveys Researchers used quantum theory – usually invoked to describe the actions of subatomic particles – to identify an unexpected and strange pattern in how people respond to survey questions. By conventional standards, the results are surprising: The scientists found the exact same pattern in 70 nationally representative surveys from Gallup and the Pew Research center taken from 2001 to 2011, as well as in two laboratory experiments. Most of the national surveys included more than 1,000 respondents in the United States. "Human behavior is very sensitive to context. It may be as context sensitive as the actions of some of the particles that quantum physicists study," said Zheng Wang, lead author of the study and associate professor of communication at The Ohio State University. "By using quantum theory, we were able to predict a surprising regularity in human behavior with unusual accuracy for the social sciences in a large set of different surveys."
Physicists Create and Control a Large Quantum Mechanical System Built on Photons A new study from Yale University shows that scientists can create and control a large quantum mechanical system built on photons, suggesting that they might be able to expand the role of photons in quantum information systems. Light might be able to play a bigger, more versatile role in the future of quantum computing, according to new research by Yale University scientists. A team of Yale physicists has coaxed an unprecedented number of light particles, or photons, to behave quantum mechanically, or to assume more than one state simultaneously, such as “alive” and “dead.” The quantum computer, a still embryonic technology, would be a hyper-fast tool with exponentially faster information processing than today’s most sophisticated computers. In current quantum computing models, scientists typically describe systems built of many artificial quantum components known as qubits. The paper is titled “Deterministically encoding quantum information using 100-photon Schroedinger cat states.”

Les champs de torsion, la clé de la « Théorie du Tout » incluant la conscience On attribue généralement la première recherche concernant la découverte du « champ de torsion » appellée aussi « 5ème force », au russe le Pr Mychkine dans les années 1800. C’est un collègue d’Einstein, le Dr Eli Cartan qui a le premier appelé cette force champ de « torsion » en 1913 en référence à ce qu’il décrivait comme des mouvements de torsion à travers la trame de l’espace-temps. Dans les années 1950, le scientifique russe d’ avant garde Dr. NA Kozyrev (1908-1983) a prouvé de façon concluante l’existence de cette énergie , en démontrant en parallèle de l’écoulement du temps la manifestation d’eune « spirale géométrique sacrée » (The Grand Illusion (TGI).) Les scientifiques russes auraient écrit près de 10.000 documents sur le sujet dans les seules années 1990. Torsion signifie essentiellement «tordre» ou «en spirale». On estime que l’inluence des champs de torsion sont capables d’influencer les états de spin. Kozyrev, le temps et la torsion Le scientifique russe Dr. Selon A. D.G.
A world first! Success at complete quantum teleportation Furusawa group at the University of Tokyo has succeeded in demonstrating complete quantum teleportation of photonic quantum bits by a hybrid technique for the first time worldwide. In 1997, quantum teleportation of photonic quantum bits was achieved by a research team at Innsbruck University in Austria. However, such quantum teleportation couldn't be used for information processing, because measurement was required after transport, and the transport efficiency was low. "In 1997, quantum bit teleportation was successfully achieved, but as I said just now, it was only achieved in a probabilistic sense. The hybrid technique was developed by combining technology for transporting light waves with a broad frequency range, and technology for reducing the frequency range of photonic quantum bits. "I think we can definitely say that quantum computers have come closer to reality.
Graviton Un article de Wikipédia, l'encyclopédie libre. Le graviton est une particule élémentaire hypothétique qui transmettrait la gravité dans la plupart des systèmes de gravité quantique. Il serait donc le quantum de la force gravitationnelle. Caractéristiques du graviton[modifier | modifier le code] Afin de répondre aux caractéristiques de l'interaction gravitationnelle, les gravitons doivent toujours mener à une interaction attractive, avoir une portée infinie et être en nombre illimité. Genèse du graviton[modifier | modifier le code] Les gravitons ont été postulés suite aux succès de la représentation des interactions dans le cadre de la mécanique quantique dans d'autres domaines. Étant donné le large succès de la mécanique quantique pour la description des autres interactions représentant les forces fondamentales de l'univers, il a semblé naturel que les mêmes méthodes devaient fonctionner pour la description de la gravitation.

Mécanique quantique Un article de Wikipédia, l'encyclopédie libre. La mécanique quantique est la branche de la physique qui a pour objet d'étudier et de décrire les phénomènes fondamentaux à l'œuvre dans les systèmes physiques, plus particulièrement à l'échelle atomique et subatomique. Elle fut développée au début du XXe siècle par une dizaine de physiciens américains et européens, afin de résoudre différents problèmes que la physique classique échouait à expliquer, comme le rayonnement du corps noir, l'effet photo-électrique, ou l'existence des raies spectrales. Au cours de ce développement, la mécanique quantique se révéla être très féconde en résultats et en applications diverses. Elle permit notamment d'élucider le mystère de la structure de l'atome, et plus globalement elle s'avéra être le cadre général de description du comportement des particules élémentaires, jusqu'à constituer le socle de la physique moderne.

Quantum mechanics Description of physical properties at the atomic and subatomic scale Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms.[2]: 1.1 It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale.[3] Overview and fundamental concepts Quantum mechanics allows the calculation of properties and behaviour of physical systems. A fundamental feature of the theory is that it usually cannot predict with certainty what will happen, but only give probabilities. . and , where Here
Quantum cryptography Quantum cryptography uses our current knowledge of physics to develop a cryptosystem that is not able to be defeated - that is, one that is completely secure against being compromised without knowledge of the sender or the receiver of the messages. The word quantum itself refers to the most fundamental behavior of the smallest particles of matter and energy: quantum theory explains everything that exists and nothing can be in violation of it. Quantum cryptography is different from traditional cryptographic systems in that it relies more on physics, rather than mathematics, as a key aspect of its security model. Essentially, quantum cryptography is based on the usage of individual particles/waves of light (photon) and their intrinsic quantum properties to develop an unbreakable cryptosystem - essentially because it is impossible to measure the quantum state of any system without disturbing that system. How It Works in Theory Bob measures some photons correctly and others incorrectly.
What is quantum superposition Quantum matter can be difficult to study. While physicists have come a long way in the research of this microscopic science, some things are still a mystery because quantum matter can behave so erratically. Einstein's theory of relativity and various other laws of physics tend to fall apart at the subatomic level of quantum physics, because photons -- or tiny particles of light -- seem to change form randomly, and possibly change simply in observation. Niels Bohr, a famous Danish physicist, proposed the Copenhagen interpretation, which revolves around quantum superposition. Quantum superposition is the term physicists use to describe the manner in which quantum particles appear to exist in all states simultaneously. Recently, scientists at the University of California, Santa Barbara, produced the first experiment in which quantum superposition in a visible object was observed.
L’hypothèse des univers parallèles gagne du terrain chez les scientifiques Publié le 23/03/2010 La théorie des univers multiples fut introduite par le physicien américain Hugh Everett en 1957. Aujourd'hui , des astrophysiciens reconnus - parmi lesquels Trinh Xuan Thuan -pense que notre univers, qui comporte aujourd'hui des dizaines de milliards de galaxies, n'aurait été à l’origine qu'une minuscule bulle perdue dans un méta univers, lui-même perdu dans des milliards de métas univers créés quelques secondes après le Big Bang et ayant donné naissance simultanément à d’innombrables mondes, mais qui nous sont inconnus ( et sans doute inconnaissables avec les méthodes de la science actuelle). Les trous noirs mèneraient vers de nouveaux univers En outre, il existe dans l'Univers des zones où l'espace-temps n'est plus mesurable par notre physique : les TROUS NOIRS; des régions qui déforment l'espace-temps et attirent irrésistiblement tout ce qui passe dans leur voisinage. Pour le moment, le déplacement physique ne peut nous mener vers un autre univers.
