Controlled Preparation of a Biexciton State in a Quantum Dot
We propose a method for the controlled preparation of a biexciton state in a single quantum dot by the application of a laser field. We analyze the dynamics of the quantum dot system under the interaction with the laser field with the time-dependent Schrödinger equation. Using the method of controlled rotation we present analytical results for the laser field parameters needed for efficient creation of the biexciton state. The effects of dephasing to the proposed method is also discussed.
