有限射影平面上作为弧的互无偏基集?

Sets of Mutually Unbiased Bases as Arcs in Finite Projective Planes?

Metod Saniga, Michel Planat

摘要:

本文是Saniga等人的猜想的一个简短的阐述(J. Opt. B:Quantum Semiclass. 6(2004)L19-L20)通过将d维希尔伯特空间中的一组相互无偏基(MUB)(d是素数的幂)视为d阶(Desklesian)射影平面中的弧的类似物。因此,MUB的完整集合对应于(d+1)-弧,即,椭圆形对于d偶数和大于4的情形,存在两种主要不同的椭圆,即二次曲线和非二次曲线,这意味着对于相应维数的希尔伯特空间,存在两组性质不同的MUB完备集。

英文摘要:

This note is a short elaboration of the conjecture of Saniga et al (J. Opt. B: Quantum Semiclass. 6 (2004) L19-L20) by regarding a set of mutually unbiased bases (MUBs) in a d-dimensional Hilbert space, d being a power of a prime, as an analogue of an arc in a (Desarguesian) projective plane of order d. Complete sets of MUBs thus correspond to (d+1)-arcs, i.e., ovals. The existence of two principally distinct kinds of ovals for d even and greater than four, viz. conics and non-conics, implies the existence of two qualitatively different groups of the complete sets of MUBs for the Hilbert spaces of corresponding dimensions.
