ed on by reasearchers today, this single quantum logic gate and it's arrangement of components to perform a particular operation. One such gate could control the switch from a 1 to a 0 and back, while another could take two bits and make the result 0 if both are the same, 1 if different. These gates would be rows of ions held in a magnetic trap or single atoms passing through microwave cavities. This single gate could be constructed within the next year or two yet a logical computer must have the millions of gates to become practical.Tycho Sleator of NYU and Harald Weinfurter of UIA look at the quantum logic gates as simple steps towards making a quantum logic network. These networks would be but rows of gates interacting with each other. Laser beams shining on ions cause a transition from one quantum state to another which can alter the type of collective motion possible in the array and so a specific frequencies of light could be used to control the interactions between the ions. One name given to these arrays has been named "quantum-dot arrays" in that the individual electrons would be confined to the quantum-dot structures, encodeing information to perform mathmatical operations from simple addition to the factoring of those whole numbers....
