Abstract

The mechanism of resonance energy transfer between quantum dots is investigated theoretically. In order to incorporate explicit account of the selection rules for absorption of circularly polarized light, a quantum electro-dynamical treatment of the electronic coupling is derived. The electronic coupling is mediated by the exchange of a virtual photon, which in the far zone limit acquires real character and is circularly polarized. The conditions by which quantum information, in terms of exciton spin orientation (total angular momentum quantum number), can be exchanged or switched through resonance energy transfer are discussed. Intrinsic exciton spin flip processes are shown experimentally to compete with typical energy transfer rates. Exciton spin flip times correspondingly range from < 100 fs to 1.2 ps are reported.
