But their ways of doing it are by the use of quantum dots under extremely cold temperature, below 1 degree Kelvin that would cause devices to be more sensitive to interference. For the UB group, they managed to trap and detect the spin at temperatures of about 20 degrees Kelvin, which is the condition that seems more promising for for the development of a viable technology. Now, they have successfully mastered the way for detecting single spin of electron, the next is to move on i.e. to figure out how to trap and detect two or more spins.

Hyperspectral imagers, for instance, that acquire data resolved not only in space but also spectrally (i.e., at many wavelengths), enable the extraction of unique characteristics, unobtainable by other means.The ongoing trend toward sensor miniaturization provides a strong incentive to develop computational capabilities for processing the rich signal information at the sensor's scale. A major step toward developing computational "brain" power to speed up the processing of signal patterns is being taken by a multidisciplinary nanotechnology project at ORNL, supported partly by internal funding from the Laboratory Directed Research and Development Program. Researchers at the Laboratory are fabricating a nanoscale pattern-recognition device, using gold nano-particles on a DNA template, which may eventually prove the feasibility of this concept.
