无相位ZH-演算的完备性

Completeness of the Phase-free ZH-calculus

John van de Wetering, Sal Wolffs

摘要:

ZH演算是量子位之间的线性映射的图形演算,允许Toffoli+Hadamard门集合的自然表示。最初版本的微积分,允许每个生成器被标记为一个任意的复数,被证明是完整的贝肯斯和基辛格。尽管微积分是完备的,但这并不意味着它允许人们在受限的环境中轻松推理,比如量子计算。在本文中,我们研究的ZH-演算的片段是无相位的,因此更接近物理上可实现的地图。我们提出了一个修改后的无相位的ZH演算的规则集,并证明了它是完备的。我们进一步讨论了该规则集的最小性,并给出了规则的直观解释。我们的完整性结果如下减少到Vilmart的无相位$Δ$ ZX演算的规则集。

英文摘要:

The ZH-calculus is a graphical calculus for linear maps between qubits that allows a natural representation of the Toffoli+Hadamard gate set. The original version of the calculus, which allows every generator to be labelled by an arbitrary complex number, was shown to be complete by Backens and Kissinger. Even though the calculus is complete, this does not mean it allows one to easily reason in restricted settings such as is the case in quantum computing. In this paper we study the fragment of the ZH-calculus that is phase-free, and thus is closer aligned to physically implementable maps. We present a modified rule-set for the phase-free ZH-calculus and show that it is complete. We further discuss the minimality of this rule-set and we give an intuitive interpretation of the rules. Our completeness result follows by reducing to Vilmart's rule-set for the phase-free $Δ$ZX-calculus.
