Atomic Quantum Dot QCA Cell 1

Caption

Four atomic quantum dots are coupled to form a "cell" for containing electrons. The cell is filled with just two electrons. Control charges are placed along a diagonal to direct the two electrons to reside at just two of the four quantum dots comprising the cell. This new level of control of electrons points to new computation schemes that require extremely low power to operate. Such a device is expected to require about 1,000 times less power and will be about 1,000 times smaller than today's transistors.
