有限维系统上的量子测量：重新标记和混合
Quantum measurements on finite dimensional systems: relabeling and mixing
摘要：
集中在有限维系统，我们表明，可以限制到极值秩1 POVMs，如果两个简单的程序的混合和重新标记是允许的。我们证明了任何有限结果的POVM可以得到从极值秩1 POVM这两个程序。特别地，具有更高秩的极值POVM只是极值秩1 POVM的重标记，因此它们的结构被澄清。
英文摘要：
Concentrating on finite dimensional systems, we show that one can limit to extremal rank-1 POVMs if two simple procedures of mixing and relabeling are permitted. We demonstrate that any finite outcome POVM can be obtained from extremal rank-1 POVMs with these two procedures. In particular, extremal POVMs with higher rank are just relabelings of extremal rank-1 POVMs and their structure is therefore clarified.
