Abstract :
A practical all optical quantum calculator/simulator is expected to need a number of gates which will be extraordinarily high. A key challenge towards the achievement of an optical quantum computer is that of a “deterministic” source of entangled photons, designed to be compatible with standard cleanroom processing and integration technology. This paper discuss how a relatively “niche” QD system (site-controlled Pyramidal quantum dots, grown by metalorganic vapour phase epitaxy in etched GaAs (111)B tetrahedral recesses) actually offer a number of unexpected potentiality for entangled photon emission.
