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...

Quantum Teleportation Team Breaks The Distance Record

April Flowers for redOrbit.com - Your Universe Online An international team of researchers, including physicists from the University of Vienna and the Austrian Academy of Sciences, has achieved quantum teleportation over a record distance of 143 kilometers. The experiment marks a major step towards satellite-based quantum communication. The team transmitted quantum states between the two Canary Islands of La Palma and Tenerife over a distance of 143 kilometers, beating the previous...

Top Physicists Come To Jerusalem To Mark 40 Years Since Jacob Bekenstein’s Famous Essay On The Entropy Of Black Holes
2012-09-04 09:53:43

Speakers include Nobel laureate and winner of new $3 million physics prize As the scientific community marks 40 years since the publication of Prof. Jacob Bekenstein's famous paper on black hole entropy, the Hebrew University of Jerusalem´s Institute for Advanced Studies is celebrating the occasion by hosting an international conference featuring the world´s top theoretical physicists. The Sep. 3-7 conference, Forty Years of Black Hole Thermodynamics, is presented in cooperation...

Quantum Computing Could Help Fight Cybercrime

Michael Harper for redOrbit.com — Your Universe Online Some of us were born naturally inclined to understand numbers and their relationships to one another. The rest of us, sadly, depend on the work of these mathematically savvy individuals just to function in everyday life. As such, while some may have no issues understanding prime numbers and calculating them in their heads, others may get a headache once they count past 10. There are computers that exist, of course, which can...

New Perception Of The Remote Control Of Quantum Systems
2012-08-06 09:50:41

A fundamental characteristic of quantum physics is the fact that two or more particles can exhibit correlations stronger than classically allowed. This unique characteristic applies particularly to quantum entanglement: as soon as the quantum state of a particle is measured the state of its entangled partner changes accordingly, regardless of how far apart the two entangled particles might be. This feature allows for the remote quantum state preparation, which is an essential ingredient for...

Information Advantage Gained From Surprising Quantum Source
2012-08-06 09:34:56

New research lends hope that a phenomenon called quantum discord could be harnessed to bring quantum technologies within easier reach than expected. The work, by an international team, is published 5 August in Nature Physics. Up until a few years ago, researchers thought that realising quantum technologies would mean harnessing the most difficult-to-tame properties of the quantum world. For example, 'entanglement', the phenomenon referred to by Einstein as spooky-action-at-a-distance, was...

Single particles of light, also known as photons, have been produced and implemented into a quantum key distribution (QKD) link, paving the way for unbreakable communication networks. The results of the experiment, undertaken by a close collaboration of researchers based in Wuerzburg, Munich and Stuttgart, have been published today, Thursday 2 August, in the Institute of Physics and German Physical Society's New Journal of Physics. The single photons were produced using two devices made...
