一个非任意量子ZW-演算

A non-anyonic qudit ZW-calculus

Quanlong Wang

摘要:

ZW演算是一种用于纯量子位量子计算的图形化语言。通过对ZW-演算完备性的转化,得到了ZX-演算完备性的第一个证明。量子比特ZW演算(任意量子比特ZW演算)的d级推广已经在[Hadzihasanovic 2017]中给出,它对于纯量子比特量子计算是通用的。然而,在这种类型的ZW-演算中,W蜘蛛的解释涉及所谓的q-二项式系数,从而使得计算相当复杂。本文给出了一种新的量子比特ZW演算,它具有类似于量子比特ZW演算的生成元和重写规则。特别是,Z蜘蛛与[Wang 2021]中给出的qudit ZX-演算完全相同,而新的W蜘蛛作为线性映射的解释要简单得多。此外,我们建立了这个量子ZW-演算和量子ZX-演算之间的一个转换,它是普适的,如[Wang 2021]所示,因此这个量子ZW-演算对于纯量子量子计算也是普适的。

英文摘要:

ZW-calculus is a useful graphical language for pure qubit quantum computing. It is via the translation of the completeness of ZW-calculus that the first proof of completeness of ZX-calculus was obtained. A d-level generalisation of qubit ZW-calculus (anyonic qudit ZW-calculus) has been given in [Hadzihasanovic 2017] which is universal for pure qudit quantum computing. However, the interpretation of the W spider in this type of ZW-calculus has so-called q-binomial coefficients involved, thus makes computation quite complicated. In this paper, we give a new type of qudit ZW-calculus which has generators and rewriting rules similar to that of the qubit ZW-calculus. Especially, the Z spider is exactly the same as that of the qudit ZX-calculus as given in [Wang 2021], and the new W spider has much simpler interpretation as a linear map. Furthermore, we establish a translation between this qudit ZW-calculus and the qudit ZX-calculus which is universal as shown in [Wang 2021], therefore this qudit ZW-calculus is also universal for pure qudit quantum computing.
