Innovative Ion Trap on a Semiconductor
Denix writes "MIT's TechnologyReview has an interesting article on a silicon-based "ion trap" in order to host a "qubit." The Ion Trap technology 'uses electric and magnetic fields to isolate a charged particle from its environment -- a prerequisite for exploiting the temperamental quantum properties of electrons."
I wonder what sort of programming language would be needed to manipulate such esoteric devices.
Jesus saved me from my past. He can save you as well.
You know I've read lots of interesting application for quantum PC-s, but they are all esoteric, like hacking encryption keys or in scientific supercomputers for .. well simulating quantum level events :)
.. well odd).
The progress is certainly interesting, but I everything shows this won't be the future of the mass computing, where running multimedia and office application are more practical usage of technology, and not especially suited for quantum computers (cuz most of you know quantum computers aren't just super fast computers.. they're just
For personal computing we gotta be looking into nano-technology, which also would be compatible with today's PC architecture (i.e. nano RAM in a laptop or nano HDD with SCSI interface for example).
The chip is placed in a vacuum, which then gets injected with a vapor of cadmium ions. When the appropriate voltages are applied to the electrodes, a cadmium ion with a free electron becomes trapped, floating between the cantilevers above the etched hole. In order to actually use the atom's free electron for computation, Monroe explains, the ion must be probed by a laser beam that reads the electron's spin state.

Is it possible for solar wind to affect the ions and electrons making these calculations?

Indeed my point.
.. different thing.
BTW this is why I always thought calling them "computers" is misleading. When you say computer you expect the full thing, being able to handle any PC tasks you throw at it.
I'd rather call it Quantum Processing Unit (QPU), and just like FPU before it it'll play together with the core CPU, not replace it, since you still need a "normal" CPU to display the interface, code editor, to compile code and to show the results of the quantum computations of the QPU.
You can't just grab a QPU and adapt it to do all tasks a moden CPU can. They're just
Why hasn't quantum computing gone further? Well, first you need to know that it requires your qubit to be tied to nearby qubits. When done with electrons, this is difficult because decoherence sets in very quickly.
In the end, they can "compute" with this string of qubits by bathing it in a certain frequency wavelength. What comes back are the multiple waves with the frequencies of all the prime factorizations of the initial frequency. The initial frequency cannot be greater than 2^(# of qubits).
The information I am relaying to you is from George Johnson's book, A Shortcut Through Time. Which is quite good.
I would also like to point out that the United States Government Lab in Los Alamos has done considerable research regarding this.
As a citizen of the U.S., you are funding this project so you have paid for and are entitled to read about their discoveries and I encourage you to do so if you have the time.
The reason for all this research? ~ From the Wiki Talk on Shor's Algorithm
My work here is dung.
Instead of addressing mass-production issues, maybe it would be time to put up a working quantum computer and see if it turns out useful. I doubt the goal of "10'000 qubits before it is useful" is impossible with today's technology.
Anyone remembers those computers that filled a whole room, and cost the price of a small country?
