如果1=2+3,那么1=2.3:贝尔态,有限群和相互无偏基,统一的方法

If 1=2+3, then 1=2.3: Bell states, finite groups, and mutually unbiased bases, a unifying approach

Thomas Durt

摘要:

研究了Bell态、有限群和完备基之间的关系。我们展示了如何获得一组N+1的基础上,贝尔状态是不变的。它们推广了X,Y和Z量子位基,并与推广泡利的sigma算子的酉变换群相关联。当维数N是一个素数的权力,我们得到(与著名的结果一致)一组相互无偏基地。我们展示了它们如何可以表示在相关的有限域的N个元素的(操作)。

英文摘要:

We study the relationship between Bell states, finite groups and complete sets of bases. We show how to obtain a set of N+1 bases in which Bell states are invariant. They generalize the X, Y and Z qubit bases and are associated to groups of unitary transformations that generalize the sigma operators of Pauli. When the dimension N is a prime power, we derive (in agreement with well-known results) a set of mutually unbiased bases. We show how they can be expressed in terms of the (operations of the) associated finite field of N elements.
