ABSTRACT
Cavity QED-based approaches have been considered some of the most
promising for practical implementation of quantum information process-
ing [1, 2]. Such quantum networks would combine the ease of storing
and manipulating quantum information in atoms, ions [3, 4], or quantum
dots [5], with the advantages of transferring information between nodes via
photons, using coherent interfaces [6-8]. So far, the remarkable demon-
strations of basic building blocks of such networks have relied on atomic
systems [9-12]. Without a doubt, a successful solid-state implementation
of such an approach would open new opportunities for scaling of practical
quantum information processing systems [5]. Among the proposed solid-
state implementations, systems comprising of quantum dots in photonic
crystals are emerging as likely the most favorable, because of the small vol-
umes of photonic crystal cavities which enable strong quantum dot-cavity
field interaction [13-15], as well as because of the ability to integrate pho-
tonic crystal components monolithically on chip [16].
