New 'Quasiparticles' Discovered; May Pave Way Toward New Quantum Computer
June 5, 2008 — Scientists have demonstrated, for the first time, the existence of "quasiparticles" with the one quarter the charge of an electron. While charges with odd denominators have been seen, the new, ... > full story -
New Design Enables More Cost-effective Quantum Key Distribution
May 30, 2008 — Researchers have demonstrated a simpler and potentially lower-cost method for distributing cryptographic keys using quantum cryptography, the most secure method of transmitting data. The new method ... > full story -
Electron Traps That Compute
May 27, 2008 — Physicists have used a semiconductor material to create superimposed quantum dots that "trap" single electrons. Not only can these dots be studied with lasers, their energy can be influenced as well. ... > full story -
Quantum Cryptography: Researchers Break 'Unbreakable' Crypto
May 11, 2008 — Quantum cryptography has been regarded as 100-percent protection against attacks on sensitive data traffic. But now a research team in Sweden has found a hole in this advanced technology. The risk of ... > full story -
Quantum Mechanical Con Game: Winning Every Time
May 6, 2008 — For the first time, physicists have come up with a scheme that would allow a quantum mechanical expert to win every time in a con game with a victim who only knows about classical physics. Prior ... > full story -
New Basic Element For Electronic Circuits: 'Memristor' Could Give Computers Memories That Don't Forget
May 1, 2008 — Researchers from HP Labs have proven the existence of what had previously been only theorized as the fourth fundamental circuit element in electrical engineering. This scientific advancement could ... > full story -
Beating The Codebreakers With Quantum Cryptography
April 29, 2008 — Quantum cryptography may be essentially solved, but getting the funky physics to work on disciplined computer networks is a whole new headache. Cryptography is an arms race, but the finish line may ... > full story -
Exotic Quantum State Of Matter Discovered
April 25, 2008 — Scientists from Princeton University have found that one of the most intriguing phenomena in condensed-matter physics -- known as the quantum Hall effect -- can occur in nature in a way that no one ... > full story -
Secure Communications Via Space
April 23, 2008 — The exchange of information between distant sources is the basis of all communications, but quantum mechanics may open up this distant exchange as never before. Quantum key distribution, for ... > full story -
What Happens When You Pop A Quantum Balloon?
April 20, 2008 — When a tiny, quantum-scale, hypothetical balloon is popped in a vacuum, do the particles inside spread out all over the place as predicted by classical mechanics? A Nature paper answers the question, ... > full story -
Creating Quantum Computers Using Entangled Photons In Optical Fibers Getting Closer
April 9, 2008 — Computer scientists are one step closer to realizing distributed quantum computing. They recently demonstrated one of the basic building blocks for distributed quantum computing using entangled ... > full story -
Innovative Atom Trap Catches Highly Magnetic Atoms, Cools Atoms To Almost Absolute Zero
April 5, 2008 — Scientists have succeeded in cooling atoms of a rare-earth element, erbium, to within two millionths of a degree of absolute zero using a novel trapping and laser cooling technique. Potential ... > full story
