Scientists Make Strides Toward Quantum Computing
2012-07-04 04:33:58

Lee Rannals for redOrbit.com - Your Universe Online Harvard scientists claim that they have solved a problem faced in quantum computing by using diamonds. One challenge quantum computing has faced is creating quantum bits that exist in a solid-state system at room temperature. Most systems rely on complex and expensive equipment designed to trap an atom or electron in a vacuum, and then cool the entire system to nearly absolute zero, or –459.67° Fahrenheit. The Harvard team...

USC scientists demonstrate that quantum computing could speed up the way web page ranks are calculated on the ever-expanding Internet Most people don't think twice about how Internet search engines work. You type in a word or phrase, hit enter, and poof — a list of web pages pops up, organized by relevance. Behind the scenes, a lot of math goes into figuring out exactly what qualifies as most relevant web page for your search. Google, for example, uses a page ranking algorithm...

Quantum Computers Move One Step Closer
2012-06-08 03:00:53

The quantum computer is a futuristic machine that could operate at speeds even more mind-boggling than the world´s fastest super-computers. Research involving physicist Mike Thewalt of Simon Fraser University offers a new step towards making quantum computing a reality, through the unique properties of highly enriched and highly purified silicon. Quantum computers right now exist pretty much in physicists´ concepts, and theoretical research. There are some basic quantum...

Efficient, Tunable Interface For Quantum Networks
2012-05-23 12:59:16

Quantum technologies promise to redefine the landscape of information processing and communication. We already live in an information age, in which vast amounts of data are sent around the world over optical fibers, but future quantum networks may be many times more powerful. These networks will require interfaces that can transfer information from quantum processors onto light particles (photons). Such interfaces will allow optical fibers to transmit information-bearing photons between...

Photons Teleported 60 Miles By Chinese Researchers
2012-05-13 04:46:18

A team of Chinese physicists have shattered the record for quantum teleportation, teleporting photons approximately six times further than the previous best, according to various news reports published Friday. A team of physicists hailing from the University of Science and Technology of China in Shanghai were able to teleport particles more than 97 kilometers, or over 60 miles, said Popular Science's Dan Nosowitz. That smashes the prior standard of more than 10 miles (16-plus...

Expert Predicts Quantum Computing Technology Could Be Near
2012-05-07 04:02:49

A prominent theoretical physicist and the co-author of a book on quantum mechanics believes that research in the field of quantum computing is rapidly progressing, and that the technology is inching ever closer to becoming a reality. In a column written for the Guardian on Saturday, Jeff Forshaw, co-author of the 2011 book 'The Quantum Universe: Everything That Can Happen Does Happen' and a professor at the University of Manchester, said, "Quantum simulations have, in the past year, really...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
