Quantum
Decoys Foil Code-breaking Attempts
Computer code-makers may soon get the upper hand on code-breakers
thanks to a new quantum cryptography method designed at the
University of Toronto. Quantum cryptography uses particles of light
to share secret encryption keys relayed through fibre-optic

 Fundamental
Limitation To Quantum Computers
Quantum computers that save their data in so-called quantum bits (or
qubits) will be confronted with a fundamental limitation. This is
the claim made by Dutch theoretical physicists from the Foundation
for Fundamental Research on Matter (FOM) and Leiden University in an
article recently published in the journal Physical Review Letters.

Television
In The Bedroom May Hurt Child's School Performance
A study of elementary school students found
that children who had television sets in their bedrooms scored
significantly lower on school achievement tests than children
without TVs in their bedrooms. Having a computer in the home was
associated with higher test scores, according to the same study,
which was conducted by researchers at the Johns Hopkins Bloomberg
School of Public Health and Stanford University.

Quantum
computers may be easier to build than predicted
A full-scale quantum computer could produce reliable results even if
its components performed no better than today's best
first-generation prototypes, according to a paper in the March 3
issue in the journal Nature* by a scientist at the Commerce
Department's National Institute of Standards and Technology (NIST).
In theory, such a quantum computer could be used to break commonly
used encryption codes, to improve optimization of complex systems
such as airline schedules, and to simulate other complex quantum
systems.

Supercomputer
installed at RIT among the world's fastest
One of the fastest supercomputers in the world and the first ever
designed specifically to study the evolution of star clusters and
galaxies is now in operation at Rochester Institute of Technology.
The new computer, built by David Merritt, professor of physics in
RIT's College of Science, uses a novel architecture to reach speeds
much higher than that of standard supercomputers of comparable size.

Organizations
need new ways to retain women in the IT workplace
In the first study of its kind to focus on college-trained IT
professional women working in positions from systems analysts to IT
project leaders, a team of Penn State researchers have found new
evidence that organizations need better policies and programs to
foster women in the IT workplace.

Software
tool finds 'needles' in data 'haystacks'
A new software tool developed by researchers at the National
Institute of Standards and Technology makes it possible to find
chemical 'needles' in data 'haystacks' without having to know
anything about the 'needle' in advance. The new software should be
especially useful for analyzing ultrapure metals--recently shown to
have superior strength, corrosion-resistance and other
properties--and for monitoring nanoscale semiconductor fabrication.

Europe's Most Powerful Supercomputer
Comes Online
May
4 -- Europe's most powerful supercomputer, known as MareNostrum,
started for the first time at a research center in Barcelona on
April 28. Built by IBM, the machine can perform 40 trillion
calculations per second. The MareNostrum has the equivalent memory
of 20,000 personal computers and its storage capacity of 233
terabytes is equal to over 4 years' worth of nonrepeating songs if
on an iPod. MareNostrum is owned by the Barcelona Supercomputing
Center, a consortium of the Spanish and Catalan governments and the
Polytechnical University of Catalonia. It will be used for research
in computer architecture, aerodynamics, biology, and genetics.
