Nothing incredible here since for sometime now we have developed switches that
perform in the femtosecond range and these most certainly exist.

No novelty here since Quantum computers have existed for sometime now.  In fact
just recently I read an article regarding a Quantum computer that I think was 7
qbits in size and solved a factoring problem successfully.  Granted this was
using only 7 qbits and the number factored was 15 but it was in fact a quantum
computer.  It appeared in a Science journal I am a member of.

I found an excerpt from a similar project IBM did not to long ago which I have
pasted here.  The reference I was referring to was an article I read in the
Science News journal.

Notice the date and the phrase quantum computer for those of you who still doubt
there existance: <s>

"SAN JOSE, Calif., December 19, 2001 - Scientists at IBM's Almaden Research
Center have performed the world's most complicated quantum-computer calculation
to date. They caused a billion-billion custom-designed molecules in a test tube
to become a seven-qubit quantum computer that solved a simple version of the
mathematical problem at the heart of many of today's data-security cryptographic
systems."

"The IBM scientists controlled a vial of a billion-billion (1018) of these
molecules so they executed Shor's algorithm and correctly identified 3 and 5 as
the factors of 15. "Although the answer may appear to be trivial, the
unprecedented control required over the seven spins during the calculation made
this the most complex quantum computation performed to date," Amer said."

Enjoy,
