我们研究了一些最近提出的noncontextuality测试的基础上量子干涉的影响,如果测试粒子传播作为开放系统中存在的高斯随机背景。我们表明,物理的一致性要求所产生的马尔可夫耗散时间演化是完全积极的。
We study how some recently proposed noncontextuality tests based on quantum interferometry are affected if the test particles propagate as open systems in the presence of a Gaussian stochastic background. We show that physical consistency requires the resulting Markovian dissipative time evolution to be completely positive.
