Intermode correlations in a quantum dot laser as a measure of inter-dot entanglement

Summary form only given.Quantum dots have recently attracted considerable attention as one possible way of realizing quantum computation. The question whether individual quantum dots are coupled to each other has become a very important topic in this context, since quantum computation relies on the entanglement of states in different dots. In this paper we present the first photon statistics investigations of a quantum dot semiconductor laser, which enable detection of the degree of coupling between individual quantum dots.
