We discuss the fibre bundle of co-adjoint orbits of compact Lie groups, and show how it admits a compatible Kähler structure. The case of the unitary group allows us to reformulate the geometric framework of quantum information theory. In particular, we show that the Fisher information tensor gives rise to a structure that is sufficiently close to a Kähler structure to generalise some classical result on co-adjoint orbits.

量子信息论中的Kähler纤维化

我们讨论了紧凑的Lie群的共伴轨道的纤维束,并说明了它如何接纳兼容的Kähler结构。ary群的情况允许我们重新构造量子信息论的几何框架。特别是,我们证明了Fisher信息张量产生了一种结构,该结构与Kähler结构足够接近,可以推广一些在共伴轨道上的经典结果。
