The quantum mechanical computers has made a great progress in recent years, but mainly because of the complexity and cost, is still in research stage. A new system proposed by a group of researchers in the Air Force and the University Florida Atlantic University, the which, though not likely to bear directly on quantum computing market could reduce the cost of construction considerably.
The system would use photons instead of electrons which do not easily interact with each other and thus do not attach the same to convey information.The traditional solution for this problem is to use an instrument called inteferometer, which allows the manipulation of photons, which, however, dramatically increases the cost. The proposed solution is to “convey” a work of the inteferometer a permanent hologram “scrambled” in a “window” from “OptiGrate” glass.This move will initially solved the problem of calibration inteferometers, but will exclude and definitely need this one and the holograms would be unchanged over the glass. In other words, planning should be hard-coded.
This does not mean that a quantum computer built with this method could be useful for specific tasks such as quantum error correction, but it does mean that it would be difficult to modulate the features of a glass “windows” will must have a large enough size to cope with anything more than small compact quantum calculations. The researchers suggest that for the moment everything is fine for understanding them from a theoretical perspective, but unfortunately not yet developed any standards. However, the model described is “resistant to environmental factors” and much cheaper, so maybe not so very long before the construction of a model.
