论文摘要
我们提出了量子Fisher估计理论的复杂场公式，该理论与复杂参数依赖性的复杂统计数据一起起作用。这说明了估计理论的主要数量和结果的新复杂版本，具体取决于复杂的参数，例如Fisher Information矩阵和Cramér-Rao界限。这在通过复杂参数描述的量子状态（作为连贯的状态或挤压状态）中的上下文中很有用。我们展示了我们的理论在与连贯状态的量子交流中的应用。
We present a complex field formulation of the quantum Fisher estimation theory that works natively with complex statistics on the dependence of complex parameters. This states new complex versions of the main quantities and results of the estimation theory depending on complex parameters, such as Fisher information matrices and Cramér-Rao bounds. This can be useful in contexts where the quantum states are described through complex parameters, as coherent states or squeezed states. We show an application of our theory in quantum communication with coherent states.
