Check out the following paper on d-separation in quantum Bayesian networks (qbnets). This one again does not cite my almost 20 years of work on qbnets or my 7 year old paper on d-separation in qbnets. To be fair, its authors do show solidarity with their fellow plagiarists Joe Henson, Raymond Lal and Matthew F. Pusey by citing their 2 week old paper.
Pienaar and Brukner proudly proclaim themselves to be members of the Physics Faculty of the University of Vienna, where, I guess, nobody is overly judgemental and it’s fine if you are a plagiarist Herr Professor Doktor.
