However being able to group QDs to enable communication among them quantum dot molecules QDMs is still extremely challenging although this field has been studied for about 20 years. Therefore in an attempt to control the lateral ordering of QDs researchers at the University of Arkansas have developed a simple hybrid technique to fabricate QD pairs QDPs and QDMs. This technique has shown promise and paves the way for investigating possible interactions between QDs taking us one step further to realizing quantum computing. An illustration of the level of control over the lateral ordering of QDs from randomly distributed QDs to QDPs and QDMs Kimberly Sablon Zhiming Wang and Gregory Salamo who leads the atom manipulation MRSEC facility at the University of Arkansas and other co-authors have taken lateral ordering of QDs to a whole new level and have devoted much effort to controlling the configuration of QDMs. Their most recent findings were reported in an article entitled Configuration control of quantum dot molecules by droplet epitaxy published in Applied Physics Letters in 2008. Self-assembly of semiconductor nanostructures has been intensively investigated Sablon explains to Nanospotlight. In fact the stranski-krastanow SK -based growth approach which is used in latticemismatch systems has made it possible to achieve a vast range of structures with control over size and density but results in a random lateral spacing of QDs which can hinder the QD functionality as a qubit in quantum computing. Therefore an alternative growth approach termed .
