semiconductor and Quantum dots

It is predicted that one day it may be possible to use the array of quantum dots driven by ultra fast laser pulse to carry out quantum information proceesing. Some semiconductors with conduction band electrons with effective mass less than 1/10th of an free electron mass this maske the size of semiconductor 10nm in the quantum limit (which makes easier to adress and manipulate individual quantum dots). This size is supposed to very useful to invernt some quantum-computers with much smaller size and weight. A paradigmshift toward direct use of the quantumproperties of information processingdevices is now underway.
