Resonance In 'Artificial Atoms' Control Quantum Communication
2013-08-06 12:26:15

University of Copenhagen - Niels Bohr Institute Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in the scientific journal Physical Review Letters. In a conventional computer, information is made up of bits, comprised of 0's and 1's. In a quantum...

An Infallible Quantum Measurement
2013-08-05 10:10:55

AlphaGalileo Foundation For quantum physicists, entangling quantum systems is one of their every day tools. Entanglement is a key resource for upcoming quantum computers and simulators. Now, physicists in Innsbruck/Austria and Geneva/Switzerland realized a new, reliable method to verify entanglement in the laboratory using a minimal number of assumptions about the system and measuring devices. Hence, this method witnesses the presence of useful entanglement. Their findings on this...

A first for the Boulder based company: training physicists to create Bose Einstein Condensates in four days. Boulder, Colorado (PRWEB) August 02, 2013 Satyendra Nath Bose and Albert Einstein in 1924 first predicted and described the quantum behavior of atoms when cooled to temperatures very close to Absolute Zero (-273.15C or -459.67F). Advances In laser cooling techniques (for which Claude Cohen-Tannoudji, Stephen Chu and Bill Phillips won a 1997 Nobel Prize) allowed Eric Cornell and...

MIT researchers expand the range of quantum behaviors that can be replicated in fluidic systems, offering a new perspective on wave-particle duality In the early days of quantum physics, in an attempt to explain the wavelike behavior of quantum particles, the French physicist Louis de Broglie proposed what he called a "pilot wave" theory. According to de Broglie, moving particles — such as electrons, or the photons in a beam of light — are borne along on...

Kids who have head start to Mathematical concepts (like Statistics, Probability, Algebra, Geometry, Time and Distance, Ratios, Proportionality, Real, and Functional Analysis) before grade 5, have an edge over the kids who were exposed to serious mathematical concepts after 8th grade. Boston, MA (PRWEB) July 24, 2013 Even though American education system is very effective in producing leaders, managers, process, and thought leaders, it is behind in producing Einstein-like mathematicians...

Quantum research pushes boundary by testing micro theory for macro objects Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects. Researchers at the University of Calgary recently made a significant step forward in this direction by creating a large system that is in two substantially different states at the same time. Until this point,...

Detection Of Single Photons Through Quantum Entanglement
2013-07-08 10:47:20

University of Innsbruck Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of the sun's atmosphere. Today we are able to gain information about diverse objects through light measurements in a similar way. Because often very little light needs to be detected for this, physicists are looking for ever more sensitive...

Groundbreaking BEC Experiments on Space Station Boulder, Colorado (PRWEB) June 26, 2013 Bose-Einstein condensates will be produced in space using a system developed and manufactured in Boulder, Colorado. ColdQuanta has already supplied the Jet Propulsion Laboratory (JPL) with elements of its physics package destined to create Bose-Einstein condensates (BEC) in the Cold Atom Lab on the International Space Station (ISS). At the heart of the system, which simplifies and expedites the...

Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and need to be modified, according to new research from University College London and the University of Gdansk Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdańsk. The work establishes new laws in the rapidly emerging field of...

Quantum Secret In Photosynthesis Uncovered
2013-06-21 11:20:36

ICFO-The Institute of Photonic Sciences The efficient conversion of sunlight into useful energy is one of the challenges which stand in the way of meeting the world's increasing energy demand in a clean, sustainable way without relying on fossil fuels. Photosynthetic organisms, such as plants and some bacteria, have mastered this process: In less than a couple of trillionths of a second, 95 percent of the sunlight they absorb is whisked away to drive the metabolic reactions that provide...

Physics

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Open Systems & Information Dynamics

Niels Henrik David Bohr (October 7, 1885 - November 18, 1962) was a Danish physicist. He made essential contributions to understanding atom structure and quantum mechanics. Born in Copenhagen, Denmark to Christian Bohr and Ellen Adler, Bohr got his doctorate at Copenhagen University in 1911. He then studied under Ernest Rutherford in Manchester, England. Based on Rutherford's theories, Bohr published his Bohr model about atom structure in 1913, introducing the theory of electrons...

Multiverse -- The term Multiverse was invented in December 1960, by Andy Nimmo, then vice chairman of the British Interplanetary Society, Scottish Branch, for a talk on the Everett many-worlds interpretation of quantum physics which had been published in 1957, to the branch. This was given in February 1961, and the word with its original definition, "an apparent universe, a multiplicity of which, go to make up the whole universe" was then first used. This was because the then dictionary...
