Physicists Produce Quantum-entangled Images
June 13, 2008 — Using a convenient and flexible method for creating twin light beams, researchers have produced "quantum images," pairs of information-rich visual patterns whose features are "entangled," or ... > full story -
How Can Quantum Physics Be Harnessed?
June 6, 2008 — The long cherished goal of applying the strange properties of quantum mechanics to the macroscopic world we inhabit has been brought closer by a series of recent developments. The exciting progress ... > full story -
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
