okaies-a quantum computer being made would be an amazing revelation for the computing industry. these computers are twice as fast as their
ormal counterparts (if we take a coin, and get the computer to check if each side is different. a
ormal computer would read one side then the other. but a quantum would read both sides at the same time. no task sharing shindig here-this is the real two-things-at-once shizzle. beating even the most competent female...
anyhoodles-i read in new scientist about a year ago that we were oh so very close to building one.
so, how come we've not got any yet? 😛
and also-how woudl they work? and do you beleive it'd be possible to build one?...

They DO exist. The only problem is that they are too small to do any interesting calculations. The best they have is a 7-bit q'comp, with which they have succesfully factorized 15 into 3 and 5. It doesn't sound like much, but it is a start.
so, how come they're just so small? and how do they work...

radiation. When you want to know if the bit is set, open the lid
and see if the cat is breathing.
The limitation on their mass production is really due to the large
number of cats needed to do any real computation.
Uhm, I read about it in the dutch magazine 'Natuurwetenschap en Techniek', the june 2004 issue. I don't remember how they work; it was quite complicated 😀. Unfortunately, I have placed the magazine somewhere I can't get to until come saturday (don't ask, it's complicated 🙄), so I don't have any tech info or URLs at the moment.
Is there any dutch person who has the same issue and would be so kind as to post some info?

i sort of understand what i just said.
