No More Loopholes For Photons
2013-04-15 14:53:36

University of Vienna A team led by the Austrian physicist Anton Zeilinger has now carried out an experiment with photons, in which they have closed an important loophole. The researchers have thus provided the most complete experimental proof that the quantum world is in conflict with our everyday experience. The results of this study appear this week in the renowned journal Nature (Advance Online Publication/AOP). When we observe an object, we make a number of intuitive assumptions,...

Einstein's "Spooky Action" Theory Could Be Tested Aboard Space Station
2013-04-10 12:02:29

April Flowers for redOrbit.com - Your Universe Online "Spooky action at a distance" is how Albert Einstein rather famously described the theory of quantum entanglement. Until now, however, experiments attempting to examine this peculiar quantum mechanical phenomenon have been limited to relatively small distances on Earth. Researchers have proposed a solution to this in a new study published in the New Journal of Physics. To test the limits of Einstein's "spooky action" and potentially...

German Researchers Take Next Step In Quantum Communications
2013-04-03 14:44:48

Brett Smith for redOrbit.com - Your Universe Online Quantum-based communications is still in its infancy, but the technology is widely expected to become used as the next generation of secure data transfer. According to a new report in Nature Photonics, a group of German physicists has announced the successful transmission of a quantum security key from an aircraft to a ground station via laser, overcoming one of the technology´s biggest hurdles: the ability to transmit and receive...

Major Step Towards Quantum 'Internet' Signaled By Laser-like Photons
2013-03-19 13:30:09

University of Cambridge The realization of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the quantum 'internet'. The number of transistors on a microprocessor continues to double every two years, amazingly holding firm to a prediction by Intel co-founder Gordon Moore almost 50 years ago. If this is to continue, conceptual and technical advances...

Einstein's 134th Birthday
2013-03-14 14:34:12

Brett Smith for redOrbit.com - Your Universe Online Albert Einstein, almost unanimously considered the greatest physicist since Sir Isaac Newton, would have turned 134 today. His legacy can still be seen in modern society — in the revelations being made by physicists around the world and by his theories that they are still struggling to comprehend. "I am convinced that (God) does not play dice." Perhaps the most prominent contemporary example of Einstein´s legacy is...

Physicists make first direct measurements of polarization states of light Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both overcomes some important challenges of Heisenberg's famous Uncertainty Principle and also is applicable to qubits, the building blocks of quantum information theory. They report their results in a paper published...

Discovery Made In The Quantum Realm
2013-03-04 13:10:40

University of California - Santa Barbara Physicists at UC Santa Barbara are manipulating light on superconducting chips, and forging new pathways to building the quantum devices of the future —— including super-fast and powerful quantum computers. The science behind tomorrow's quantum computing and communications devices is being conducted today at UCSB in what some physicists consider to be one of the world's top laboratories in the study of quantum physics. A team in the...

Researchers Believe Quantum Satellites Will Be The Next Space Race
2013-03-01 20:16:16

Lee Rannals for redOrbit.com — Your Universe Online Two researchers from the University of Waterloo, Canada say the next big space race is building the first global quantum-communication satellite network. Up until now, the furthest quantum-communication signals have traveled is just a few hundred miles. However, this technology is up-and-coming, and is what Thomas Jennewein and Brendon Higgins believe will be driving the next space race. Quantum communication is the science...

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...
