A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific journal Nature Physics. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology. One huge advantage of such...

New 'Quantum Key Distribution' System Safeguards Secrets, Works In The Real World
2013-09-04 13:00:43

University of Calgary University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets. The team's research – published in the journal Physical Review Letters back-to-back with similar work by a group from Hefei, China – also removes a big obstacle to realizing future applications of quantum communication, including a fully functional quantum network. "I hope...

Door Opened For Solid State Physics By Berlin Researchers

Helmholtz Association Laser processes observed with X-rays on a solid Without the currently available plethora of X-ray methods, basic research in the physical sciences would be unthinkable. The methods are used in solid state physics, in the analysis of biological structures, and even art historians have X-rays to thank for many new insights. Now, scientists at the Helmholtz Center Berlin (HZB) have identified yet another area of application. The team around Dr. Martin Beye and Prof....

University of Rochester [ Watch The Video - Floating Nanodiamonds Light Measured For First Time ] Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. In a paper published this week in Optics Letters, they describe how they used a laser to trap nanodiamonds in space, and – using another laser – caused the diamonds to emit light at given frequencies. The experiment, led by Nick...

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, are always present. Always, that is, unless you can pull off a quantum trick. And that's just what a team led by researchers at the California Institute of Technology (Caltech) has done. The group has engineered a miniature silicon system...

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,...

“Why? The Single Photon Theory” explains the nature of time, space and consciousness. PUERTO RICO (PRWEB) July 22, 2013 For author Zaid Díaz Gandía, the mounting suffering of a blighted civilization has finally become unbearable. The anguish of a society lost in the delirious twists and turns of a febrile world has prompted him to publish his interpretation of reality’s nature. Why? The Single Photon Theory is an existential interpellation stemming from six decades of...

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...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...

Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...

conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
