Data ‘Repair Kit’ for Quantum Computers
A practical method for automatically correcting data-handling errors in quantum computers has been developed and demonstrated by physicists at the
National Institute of Standards and Technology (NIST).
Described in the Dec. 2, 2004, issue of the journal Nature, the NIST work is the first demonstration of all the steps of error correction for quantum
computers, a futuristic, potentially very powerful form of computing that uses the quantum properties of atoms or other particles as 1s and 0s for
processing data. The method was implemented using ions (electrically charged atoms) as quantum bits (qubits). Ions are arguably the leading candidate
for use as qubits in a quantum computer.
Also the coming atomic age..
Unveiled recently before a group of true believers in bottom-up molecular assembly (as opposed to products such as stain-free pants and carbon
nanotube tennis rackets being sold as "nanotechnology"), the partly finished "Productive Nanosystems: From Molecules to Superproducts" is meant,
in part, to show that all this talk of futuristic-sounding molecular manufacturing is capable of producing a real product, too -- someday.
The product: "A billion-processor laptop computer," Drexler says, built atom by atom on a contraption that looks, at least in the animation, a bit
like your average office copy machine......
Computational Nanotechnology: The emerging ability to economically arrange atoms in most of the ways permitted by physical law will revolutionize
manufacturing. This will broaden the theoretical and computational aspects of molecular nanotechnology, and some of the wider implications. Topics
include a brief survey of basic physics and chemistry relevant to molecular machines, issues in the design and development of such machines and some
proposals, and possible applications to (for example) computers, materials, medicine, space, etc...
This is come a long way from the gecko's toe through the deep vision of J.Van Der Waals,whowas a Dutch scientist famous "for his work on the
equation of state for gases and liquids", for which he won a Nobel Prize in 1910. Van der Waals interactions are observed in nobel gases, which are
very stable and tend not to interact, that is why it is difficult to condence them into liquids. However, the larger the molecule of the noble gas
(the more electrons it has), the easier it is to condense the gas into a liquid.
