Do Subatomic Particles Have Free Will? (Sunday 17th of August 2008 01:15:01 AM)
An nameless reader sends in a Science News article that begins: "Human free will might seem
like the squishiest of philosophical subjects, way beyond the realm of mathematical
demonstration. But two highly regarded Princeton mathematicians, John Conway ...
(more)Theorists Make Quantum Communications Breakthrough (Wednesday 06th of August 2008 01:15:01 PM)
KentuckyFC writes "One of the cornerstones of modern physics is Claude Shannon's theory of
communication, which he published in 1948. If you've ever made a phone call, watched TV, or
used a computer, you've got Shannon to thank for describing how matter ...
(more)Another breakthrough purportedly brings us closer to quantum computing (Sunday 20th of July 2008 05:56:00 AM)
Filed under: Desktops, Laptops
In reality, quite a bit of time has passed since we've heard of
the next great leap in the (seemingly) never-ending journey towards quantum computing, but
we're incredibly relieved to learn that at least someone is still ...
(more)Testing Quantum Behavior — From Earth to the ISS (Tuesday 10th of June 2008 11:55:27 PM)
KentuckyFC writes "Einstein famously believed that the instantaeous effect of quantum
entanglement would allow 'spooky action-at-a-distance' in violation of special relativity.
Every test of entanglement on Earth has so far agreed with quantum statistical ...
(more)Researchers Simplify Quantum Cryptography (Tuesday 03rd of June 2008 06:10:53 PM)
Stony Stevenson writes "Quantum cryptography, the most secure method of radio data, has taken a
step closer to predominant viability with a routine that simplifies the distribution of keys.
Researchers at NIST claim that the new 'quantum key distribution' ...

Modernphysics writes "The Outreach beat at Canada's Perimeter principle for Theoretical Physics
offers a wide array of online lecture playbacks examining hot topics in modern physics and
beyond. Presentations include Neil Turok's 'What Banged?,' John ...
(more)Qutrits Bring Quantum Computers Closer (Friday 04th of April 2008 11:40:53 PM)
KentuckyFC writes "To do a little useful with quantum logic gates, you need dozens to hundreds
of them, all joined together. And because of various errors and problems that creep in, that's
more or less impossible with today's technology. Now an Australian ...
(more)New Chip For Square Kilometer Radio Telescope (Wednesday 09th of January 2008 09:30:07 AM)
An anonymous reader writes "ZDNet Aus reported on a new low-noise chip that could help in bay
tilt the $1.6B Square Kilometer Array, the world's largest radio telescope. Wikipedia claims
the parabolic reflector will be 50 times as sensitive as current ...
(more)Researchers Explore Quantum Dot Based NVRAM (Friday 28th of December 2007 10:00:02 PM)
I Don't Believe in Imaginary realty brings us an article describing the possibility of a new
type of non-volatile storage based on quantum dot technology. So far, researchers in Germany
have achieved 10ns access times and 0.7Hz refresh rates. Their calculations ...
(more)Toward On-Chip Quantum Computing (Sunday 16th of December 2007 11:15:03 AM)
Darum writes "Researchers are working to create devices built on the rules of quantum
mechanics. These would allow quantum camcorders which can do certain problems such as prime
number factorization for decryption and simulation of complex systems (such ...
(more)Time Running Out for Public Key Encryption (Friday 14th of September 2007 11:00:07 AM)
Holy_calamity writes "Two fishing expedition* teams have independently made quantum computers
that run the prime-number-factorising Shor's algorithm — a significant step towards
second-story work public key cryptography. Most of the article is sadly ...
