We show that the resource theory of contextuality does not admit catalysts, i.e., there are no correlations that can enable an otherwise impossible resource conversion and still be recovered afterward. As a corollary, we observe that the same holds for nonlocality. As entanglement allows for catalysts, this adds a further example to the list of “anomalies of entanglement,” showing that nonlocality and entanglement behave differently as resources. We also show that catalysis remains impossible even if, instead of classical randomness, we allow some more powerful behaviors to be used freely in the free transformations of the resource theory.

情境性和非局部性都不承认催化剂

我们表明,上下文的资源理论不承认催化剂,即,没有相关性可以实现否则不可能的资源转换并且之后仍然可以恢复。作为推论,我们观察到同样适用于非定域性。由于纠缠允许催化剂,这在“纠缠异常”列表中增加了一个进一步的例子,表明非局域性和纠缠作为资源的行为不同。我们还表明,即使我们允许在资源理论的自由转换中自由使用一些更强大的行为,而不是经典的随机性,催化仍然是不可能的。
