本文定义了几种新的图的量子色数，并将它们用算子系张量积表示。我们建立这些色数和其他参数的图在文献中研究的不平等，并展示它们之间的联系和非信号相关盒。
We define several new types of quantum chromatic numbers of a graph and characterise them in terms of operator system tensor products. We establish inequalities between these chromatic numbers and other parameters of graphs studied in the literature and exhibit a link between them and non-signalling correlation boxes.
