Work on this has been ongoing for a while now but it is a slow process because of the difficulty involved in controlling large numbers of individual atoms. I recently read Michio Kaku's book "Parallel Worlds" which has a small section on quantum computers and according to him it has only been possible to control 5 or 6 atoms. Unfortunately this amount is only powerful enough to calculate 4*3=12. To make a processor equivalent to an AMD or Pentium chip of today it is suggested that one would need to control around a thousand. The atoms themselves have to be housed in an extraordinarily stable environment, where magnets are used to control the spins of the atoms. This is extremely difficult and will have to be solved before we can even think about owning one at home.

One of the most interesting aspects of quantum computers is the spectacular realisation that their massive potential power output can be achieved by utilising the fact that the electrons pass through multiple dimensions. Indeed, for the first time since Nikolai Tesla tried (succeeded?) to create his zero-point energy device, we can hopefully start using the latent, potentially infinite resourses that are contained within the universe itself. In my opinion it will be at least another 20 years before we start seeing the benefits of this new technology.

I am conducting research on optical vortex solitons right now and they contain some very interesting properties (like topological charge) that could make them extremely useable for quantum computing. These vortex solitons may be controllable in a magnetic field (simulations are currently underway).

Further research is also underway about subwavelength transmission. If photonic computers are to come of age, this is a vital step otherwise computers will be enormous in size to make the components comparable to the wavelength of light. Left-handed metamaterials are believed to be the way forward as any dispersion caused by subwavelength transmission is 'undone' by the negative index.

qubits or Qbits for short are the particles that are being used to define and is currently the particle used for quantum computing. This allows them to create a generalized theory of quantum computation and quantum information.
These techniques right now are starting to be well developed though in very preliminary way for the understanding of quantum computing, quantum algorithms, quantum cryptography, quantum error correction of data and the like.

Yeah it's because the forces between particles are mediated by other particles. The electromagnetic force between two electrons is caused by an exchange of photons. Intermediate vector bosons mediate the weak force and gluons mediate the strong force. Then a graviton particle mediates it.

sure can I can't wait to buy a quantum computer end less memory and very small

Yes. Or maybe no.
