Controlling Artificial Atoms
Science
26-JAN-99
By Antigoni Alexandrou
Semiconductor quantum dots are fascinating objects. They contain up to
a few hundred thousand atoms yet behave in many ways like one single
gigantic atom. Their unique optical and transport properties are just
being explored, but they already offer great promise for the
development of extremely low threshold laser diodes, single-electron
logic devices, or optical computing quantum units. As reported on page
1473 of this issue, Bonadeo et al. (1) have now achieved a remarkable
degree of control of the quantum states of individual "artificial
atoms."
