混合态分解相关演化的几何

Geometry of decomposition dependent evolutions of mixed states

David Kult, Erik Sjöqvist

摘要:

我们研究一个给定的混合量子态的分解的每个组件的演化独立地在一个单一的方式。这种类型的分解依赖的演化的几何相位和平行输运条件划定。我们比较这个几何相位与以前定义的酉演化的混合状态,和混合状态演化完全正的地图。

英文摘要:

We examine evolutions where each component of a given decomposition of a mixed quantal state evolves independently in a unitary fashion. The geometric phase and parallel transport conditions for this type of decomposition dependent evolution are delineated. We compare this geometric phase with those previously defined for unitarily evolving mixed states, and mixed state evolutions governed by completely positive maps.
