Re: Quantum Computing...

I love physics now, so I don't mind physics now.

Re: Quantum Computing...

In order to research a way to build a quantum computer, you probably need to have expertise in quantum physics; but if one day such a quantum computer is build, probably all you'll need is the understanding of how much machine can be exploited (in the same way as we can very well understand how a computer processor functions with all its registries, bits of memory, etc ... without having to actually understand the physical/mechanical dynamics behind all of this ...)

Re: Quantum Computing...

Indeed. Quantum physics is definitely important in order for one to deeply understand the concepts (especially theoretical) behind quantum computers.

Re: Quantum Computing...

it is the first time for me to hear the Quantum Computing.i specially looked it up on google.it could speeds up the computering,faster than the common computer.however, to the problem you asked ,i did not find the actual figure.

Yes, quantum computing can speed up computer super fast compared to a regular computer. And now I love to study physics!

Re: Quantum Computing...

I agree with what you say. Am here to talk about general Computing. Computing conference will be very much helpful and useful for the people in the Computing Industry and Software industry. By the way I too have participated in the Conference which is the World’s largest and virtual conference on Cloud Computing. Cloud Computing Conference 2010 or cloudslam10 is the event covering latest trends and innovations and technologies of the Cloud Computing. Cloudslam conference is the 2nd annual conference on cloud computing. I got a good opportunity to meet and talk with the world's leading experts of Cloud Computing.

Re: Quantum Computing...

I have recently read the Princeton definition in their book on Mathematics, I describes that all that is needed is the correct quantum field to be produced to create a quantum computer. Shortly after my mind was racing and became full of thoughts. My background is in photonics and I have always disregarded quantum computing because I believed optical based computers would out perform them, well they do, but for certain things like calculating a Fast Fourer Transform quantum computers are really fast. So my mind came up with a new novel idea of creating a quantum computer device not much different then regular computer chips. Here is the design and it's an optical system that relies on interference:

The base sub-straight is composed of a matrix of white light micro lasers the laser array is build like a city of pyramids that allow each step of teh pyramid to create a distinct beam of laser light, this like in the array can be activated and varied in intensity or digitally.

next the light from the array is passed through a thin convex optic to create positive and negative interference between the beams of light, since all the lasers are made from the same sub-straight the will in facf interfere unlike normal lasers which will not interfere because they come from a material which is not directly quantimly entangled with each other. Nice thing about this stage of the device is that different optic components can be used to create the interference pattern, this becomes important in the next two steps.

next an array of prism like pezio-electric devices are created which refract a portion of the light. The pezio crystal array can be designed so that many vectors can be refracted producing multicolor interference, which is actually a map to the quantum state of the lasers that emitted the light, don't ask me to explain how I now this just trust me. So you could have prisms that expand on the quadrants of each bit of the matrix allowing for even further computational freedom.

Next a highly sensitive CCD like a 12 mega pixel camera array is created in the same way the lasers are created in a pyramid step matrix, this is where the quantum field will collapse and we measure the results of a frame of the computation.

Last an x,y occlator is merged between the pezio array and the lasers, this allows for scanning the quantum field. The quantum field is really nothing more then an active hologram with a little refractive magic to disassemble the quantum field.

Vola' you have a powerful quantum computer chip which is ready to have data fed into it. Don't ask me how to feed it the correct coordinates for doing an FFT or any other computation, that would take much research in number theory which is beyond the scope of this abstract.

Of course you'd have to know quantum mechanics. Just tell me how much of this makes sense to you without knowing quantum mechanics:

Actually you can learn Quantum Computer science with absolutely no knowledge of physics at all. Most of the important results in Quantum Computation are unlikely to be realised in practice for many years, for a start.
