Abstract
The search for quantum coherent manifestations at a macroscopic length scale is intense nowadays. Specially, based on the fabrication of semiconductor nanostructures is now possible a level of space and time control with which those astonishing quantum effects could be demonstrated. In this paper a critical review on recent results concerning the generation of entangled states in quantum dot systems, the observation of their decoherence on a picosecond scale of time as well as the transfer of coherences from a quantum macroscopic state such as a Bose-Einstein condensate to the light it emitts is presented.
