2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/184738We study how some recently proposed noncontextuality tests based on quantum interferometry are affected if the test particles propagate as open systems in presence of a gaussian stochastic background. We show that physical consistency requires the resulting markovian dissipative time-evolution to be completely positive.23 pages, plain-TeX, no figuresQuantum PhysicsHigh Energy Physics - Theorytext
