摘要

虚数在量子力学中发挥着重要作用。最近，人们建立了量子态虚数的严格资源理论，并提出了几种虚数度量方法。在这项工作中，我们提出了一种基于 Tsallis 相对熵的新意象度量。这种意象度量有明确的表达式，而且对于玻色高斯态是可计算的。

Quantifying the imaginarity of quantum states via Tsallis relative entropy

Imaginary numbers play a significant role in quantum mechanics. Recently, a rigorous resource theory for the imaginarity of quantum states were established, and several imaginarity measures were proposed. In this work, we propose a new imaginarity measure based on the Tsallis relative entropy. This imaginarity measure has explicit expression, and also, it is computable for bosonic Gaussian states.
