Digital Encryption At The Quantum Level
2012-11-20 10:38:18

Michael Harper for redOrbit.com — Your Universe Online Toshiba and Cambridge University have been working together to find a cheaper and more efficient way to protect networks from criminal thievery and spying. To find the answer, these two teams looked to quantum physics, landing on a solution which allows high-speed fiber cables to be just as secure as dedicated fiber optics lines. Though this advance will likely first appear in government and military networks, this method could...

Griffith Uni researchers lead light breakthrough Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise. The research collaboration, involving Griffith University, The University of Queensland and University of Science and Technology of China, was able to amplify the noisy quantum state of a single photon subjected to loss, without adding noise in the process; in fact, their amplification reduced...

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...

Information breach may be drastically reduced as a result of a technology breakthrough Move over money, a new currency is helping make the world go round. As increasing volumes of data become accessible, transferable and, therefore, actionable, information is the treasure companies want to amass. To protect this wealth, organizations use cryptography, or coded messages, to secure information from "technology robbers." This group of hackers and malware creators increasingly is becoming more...

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...

Quantum Teleportation Team Breaks The Distance Record
2012-09-06 11:12:39

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...

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...
