While some theoretical physicists make predictions about astrophysics and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Such is the case at UC Santa Barbara, where theoretical physicists at the Kavli Institute for Theoretical Physics (KITP) cover the range of questions in physics. Recently, theoretical physicists at KITP have made important strides in studying a concept in quantum physics called quantum entanglement, in...

Quantum Kiss Changes Color Of Space
2012-11-08 11:16:07

April Flowers for redOrbit.com - Your Universe Online Our world is made of color, even the empty gaps have a color of their own. The findings of this study, published in the current issue of Nature, set a fundamental quantum limit on how tightly light can be trapped. The Cambridge team collaborated with scientists from the Donostia International Physics Center (DIPC), the Materials Physics Center in Donostia-San Sebastián (CFM) and the  University of Paris-Sud to...

Looking Beyond Space And Time To Cope With Quantum Theory

Centre for Quantum Technologies at the National University of Singapore Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behavior of the Universe. The proposal comes from an international team of researchers from Switzerland, Belgium, Spain and Singapore, and is published today in Nature Physics. It is based on what the researchers call a 'hidden influence inequality'. This exposes how quantum predictions challenge our best...

A research team from the University of Bristol's Centre for Quantum Photonics (CQP) have brought the reality of a quantum computer one step closer by experimentally demonstrating a technique for significantly reducing the physical resources required for quantum factoring. The team have shown how it is possible to recycle the particles inside a quantum computer, so that quantum factoring can be achieved with only one third of the particles originally required. The research is published in...

Quantum Computing And Mechanics See Two Breakthroughs
2012-09-20 13:22:33

April Flowers for redOrbit.com - Your Universe Online Two new studies, both published in Nature this week, outline incredible breakthroughs in the field of quantum mechanics. Australian engineers led an international team of researchers to create the first working quantum bit based on a single atom in silicon, potentially making another important step toward ultra-powerful quantum computing that theoreticians have dreamt of for decades. The team describes how they were able to read...

April Flowers for redOrbit.com — Your Universe Online Since 1927, when Werner Heisenberg formulated the uncertainty principle, it has stood as one of the cornerstones of quantum mechanics. In a simplified form, the uncertainty principle states that it is impossible to measure anything without disturbing it. For example, any attempt to measure a particle's position must randomly change its speed. For clarity's sake, one should be aware that the uncertainty principle is not the same...

Classical Physics: Breaking The Limits
2012-06-07 09:24:12

With simple arguments, researchers show that nature is complicated! Researchers from the Niels Bohr Institute have made a simple experiment that demonstrates that nature violates common sense — the world is different than most people believe. The experiment illustrates that light does not behave according to the principles of classical physics, but that light has quantum mechanical properties. The new method could be used to study whether other systems behave quantum mechanically. The...

Quantum communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two atomic systems. Entanglement between two atomic systems is very fragile and up until now researchers have only been able to maintain the entanglement for a fraction of a second. But in new experiments at the Niels Bohr Institute researchers have succeeded in setting new records and...

Researchers have changed one of the most basic rules of quantum mechanics: observing light behaving as both a wave and a particle -- a "complementarity" rule that asserts that it is impossible to do, even though it is strictly both.In an experiment reported in the journal Science, researchers say the feat "pulls back the veil" on quantum reality in a way that was thought to be prohibited by theory.Quantum mechanics, a counterintuitive branch of physics that deals with atomic-scale...

Researchers from the Niels Bohr Institute at the University of Copenhagen have succeeded in storing quantum information using two 'entangled' light beams. Quantum memory or information storage is a necessary element of future quantum communication networks. The new findings are published in Nature Physics. Quantum networks will be able to protect the security of information better than the current conventional communication networks. The cornerstone of quantum communication is a phenomenon...

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...

  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
