I only get  hits on Google for the phrase quantum systemics no matches with the physics preprint archivXorg and no matches on the American Physical Societys Phys Review series of journals  I wouldnt call this a recent worldwide acceptance of quantum systemics  In fact I can find very few references to the word systemics in any physics journals whatsoever and indeed very few references to systemics in any Englishlanguage scientific journals  The phrase systemics is far more widely interpreted at least in the Englishspeaking world as referring to systems theory as developed by Bertalanffy Ashby and others  Systemics is listed as an alias for systems theory so people who use the Systemics will find the page
