A world first! Success at complete quantum teleportation

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. So, quantum teleportation was still a long way from practical use in quantum communication and quantum computing. "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. Related:  Sciences quantiquesLight and energy

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.

Nuclear fusion milestone passed at US lab 7 October 2013Last updated at 17:25 ET By Paul Rincon Science Editor, BBC News website The achievement is the first of its kind anywhere in the world Researchers at a US lab have passed a crucial milestone on the way to their ultimate goal of achieving self-sustaining nuclear fusion. Harnessing fusion - the process that powers the Sun - could provide an unlimited and cheap source of energy. But to be viable, fusion power plants would have to produce more energy than they consume, which has proven elusive. Now, a breakthrough by scientists at the National Ignition Facility (NIF) could boost hopes of scaling up fusion. NIF, based at Livermore in California, uses 192 beams from the world's most powerful laser to heat and compress a small pellet of hydrogen fuel to the point where nuclear fusion reactions take place. This is a step short of the lab's stated goal of "ignition", where nuclear fusion generates as much energy as the lasers supply. Continue reading the main story Nuclear fusion at NIF

D-Wave Systems D-Wave Systems, Inc. is a quantum computing company, based in Burnaby, British Columbia. On May 11, 2011, D-Wave System announced D-Wave One, labeled "the world's first commercially available quantum computer," operating on a 128 qubit chip-set[1] using quantum annealing [2][3][4][5] to solve optimization problems. In May 2013 it was announced that a collaboration between NASA, Google and the Universities Space Research Association (USRA) launched a Quantum Artificial Intelligence Lab based on the D-Wave Two 512 qubit quantum computer that would be used for research into machine learning, among other fields of study.[6] The D-Wave One was built on early prototypes such as D-Wave's Orion Quantum Computer. Technology description[edit] D-Wave maintains a list of peer-reviewed technical publications on their website, authored by D-Wave scientists and by third party researchers. History[edit] Orion prototype[edit] According to Dr. 2009 Google demonstration[edit] D-Wave One computer system[edit]

Meet the people who want to build our first starship Really? Let's talk about a mature nanotechnology system that is solar powered, works at room temperature, largely recycles itself, and evolves to meet new situations. In case you haven't twigged, it's our own biosphere. Us. Yes, I've got a first edition copy of Drexler's Engines of Creation, so I'm not unfamiliar with the dreams of nanotech. Thing is, cells are so complex that we've got an enormous industry that's devoted entirely to reverse engineering them and hacking them (the biotech industry). Nanotechnology isn't magic fairy dust, and assuming that it will automatically solve all our problems is foolish. For example: Fusion reactors have the fundamental problem of going from thousands or millions of degrees (the fusion reaction) to close to absolute zero (the supercooled magnets making the fusion bottle) in a few meters. Similarly, making matter go from interstellar speeds to zero in a few meters (a shield against interstellar debris) is hard. And so forth and so on.

Molten air – a new class of battery The molten air batteries combine useful characteristics from existing types of batteries © Shutterstock Scientists from the US have invented a new type of battery. The so-called ‘molten air batteries’ have among the highest electrical storage capacities of all battery types to date. Inexpensive batteries with better energy storage densities are needed for many applications. Stuart Licht and his group at George Washington University think their molten air batteries could be the answer. Another important advantage of molten air batteries is that, unlike some other high energy batteries, the molten air battery is rechargeable. ‘The high storage capacity of these batteries is extraordinary to observe,’ says Licht. ‘This is the first report of a rechargeable high temperature air battery,’ says Derek Fray, a molten salts expert at the University of Cambridge in the UK.

Quantum world record smashed 14-Nov-2013 [ Print | E-mail ] Share [ Close Window ] Contact: University of Oxford Press Officepress.office@admin.ox.ac.uk 44-186-528-3877University of Oxford A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers. An international team including Stephanie Simmons of Oxford University, UK, report in this week's Science a test performed by Mike Thewalt of Simon Fraser University, Canada, and colleagues. In the experiment the team raised the temperature of a system, in which information is encoded in the nuclei of phosphorus atoms in silicon, from -269 °C to 25 °C and demonstrated that the superposition states survived at this balmy temperature for 39 minutes – outside of silicon the previous record for such a state's survival at room temperature was around two seconds. There is still some work ahead before the team can carry out large-scale quantum computations.

Dead stars 'to guide spacecraft' 30 March 2012Last updated at 12:28 ET By Jonathan Amos Science correspondent, BBC News, Manchester Spacecraft could one day navigate through the cosmos using a particular type of dead star as a kind of GPS. German scientists are developing a technique that allows for very precise positioning anywhere in space by picking up X-ray signals from pulsars. These dense, burnt-out stars rotate rapidly, sweeping their emission across the cosmos at rates that are so stable they rival atomic clock performance. This timing property is perfect for interstellar navigation, says the team. If a spacecraft carried the means to detect the pulses, it could compare their arrival times with those predicted at a reference location. "The principle is so simple that it will definitely have applications," said Prof Werner Becker from the Max-Planck Institute for Extraterrestrial Physics in Garching. Prof Becker has been describing his team's research here at the UK National Astronomy Meeting in Manchester.
