By constructing a quantum-control-assisted multipartite uncertainty relation, a general and efficient multipartite entanglement structure resolution analyzer is provided for all pure states with arbitrary number of parties in arbitrary finite dimension. The lower bounds of this multipartite uncertainty relation present different spectra for different multipartite entanglement structures, and they thus can be considered as a form of resolution analyzer for the multipartite entanglement structure. The resolution analyzer obtained delineates the detailed structure of multipartite entanglement with a suitable number of incompatible measurements, without a complete prior knowledge of the quantum state.

基于量子控制辅助多分不确定关系的多分纠缠结构解析分析仪

通过构造量子控制辅助的多分不确定关系,为任意有限维中任意多方的所有纯态提供了通用且高效的多分纠缠结构解析分析器。这种多分不确定性关系的下界为不同的多分纠缠结构呈现不同的光谱,因此它们可以被认为是多分纠缠结构的分辨率分析器的一种形式。获得的分辨率分析仪通过适当数量的不兼容测量描绘了多部分纠缠的详细结构,而无需完整的量子态先验知识。
