| Abstract: | We show that three initially nonresonant quantum dots (QDs) could be used to generate W-type entangled states with the application of a single detuned light via the ac Stark effect. This gives a way to prepare the highly entangled excitonic states in the picosecond time scale by controlling the interactions between QDs. |
