两个量子比特的互补约化

Complementary reductions for two qubits

Denes Petz, Jonas Kahn

摘要:

关于两个量子比特的最佳状态确定,提出了关于成对互补还原的最大数量的问题。本文的主要结果是:最大数为4,即如果A1,A2,…Ak是所有4 × 4矩阵代数的两两互补(或拟正交)子代数,且它们同构于所有2 × 2矩阵代数,则k至多为4。在获得这一结果的过程中,有助于理解互补还原的结构。

英文摘要:

In connection with optimal state determination for two qubits, the question was raised about the maximum number of pairwise complementary reductions. The main result of the paper tells that the maximum number is 4, that is, if A1, A2,... Ak are pairwise complementary (or quasi-orthogonal) subalgebras of the algebra of all 4x4$ matrices and they are isomorphic to the algebra of all 2x2 matrices, then k is at most 4. In the way to this result, contributions are made to the understanding of the structure of complementary reductions.
