Tiny Holes Advance Quantum Computing
Nick writes "Worldwide, scientists are racing to develop computers that exploit the quantum mechanical properties of atoms - quantum computers. One strategy for making them involves packaging individual atoms on a chip so that laser beams can read quantum data. Scientists at Ohio State University have taken a step toward the development of quantum computers by making tiny holes that contain nothing at all. The holes - dark spots in an egg carton-shaped surface of laser light - could one day cradle atoms for quantum computing." -
Web Quantum Computer Simulator
Heraklit writes "As reported on Heise News, the Frauenhofer Institute of Computer Architecture and Software Technology has made available the first online quantum computer simulator - it will be simulating up to 31 quantum bits, for testing new advanced quantum algorithms. Behind the scenes, it is a 32 node Athlon 3200 Myrinet Linux Cluster with 56GByte RAM! Now imagine the computing power of a few hundred qubits, if ever constructed..." -
IBM Builds A Limited Quantum Computer
phr1 writes "IBM has announced and Yahoo has noted that the first working implementation of Shor's factoring algorithm. Using NMR techniques they built a seven-qubit quantum computer and factored the number 15 into the factors 3 and 5. This is by far the most complicated quantum computation ever done. It's quite an amazing feat--many people thought quantum computing was just a theoretical curiosity and Shor's algorithm could never be implemented in practice." -
Quantum Mechanics Symposium
Alien54 writes "As reported in Wired Magazine, the first Quantum Mechanics Symposium is being held in Ann Arbor, Michigan. Topics to be discussed include Quantum Computing. Also to be discussed will be Atomic Lasers, a technology involving a coherent and tightly focused beam of atoms that was first developed by MIT researchers in 1997. One of the things that they could lead to is making a 3-D matter hologram using atom lasers. [not just make a 3-D image, but an actual replicate object]. Missing will be a talk by Stuart Hameroff, associate director of the University of Arizona's Center for Consciousness Studies, who recently had to cancel his appearance at the conference for personal reasons." -
Big Step in Quantum Searching
Penguin_99 writes "Wired.com has an article about a Lucent Technologies' Bell Labs researcher (Lov Grover) who came up with a quantum algorithm that is able to instantly search a massive database (of websites or whatever you might have) and return amazingly precise results even if the input is vague or incomplete. This particular algorithm can be used for other things besides searching for instance solving equations. Apperently this algorithm is only one of a handful of quantum algorithms in existance. The down side is that it requires a quantum computer so you are not likely to see Yahoo! using it anytime soon. Imagine a day when you do not have to wade through pages of usless websites after performing a search. "
