For now, the genuine computers of quantum are the substance of the science fiction - in film transformers of the bomb of large gauges the last summer , the quantum of use of bad types calculating to flat break in blocked files of the UNITED STATES Army as Juste 10 seconds.

But Prem KUMAR, professor of AT&T of technology information in the department of electrical engineering and the data processing and the director of the center for the communication and the calculation of Photonic, and its group of research are a stage more close carrying out this technology - however for much better goals. The group recently showed one of the basic building blocks for the distributed quantum calculating by using the empêtrés photons produced in optical fibres, and their research was reported in the edition April of 4 of the physical letters of review.

Because it is made with fibre and technology which already is deployed overall, we believe that it is a significant stage by arming the power with the computers of quantum that, KUMAR known as.

The calculation of Quantum differs from traditional calculation becausea traditional computer functions beside treating the bits which exist in two states, one or zero. Little calculation of quantum of uses of Quantum, or qubits, which, in more of being one or zero can also be in a superposition, which are one and zero simultaneously. It is possible because the qubits are units of quantum like atoms, ions, or photons which function according to rules' of quantum mechanics instead of traditional mechanics.
