摘要:

本文是近期工作(Yin Chen和Runxuan Zhang,自对偶NRT码的形状枚举式,SIAM J. Discrete Math. 38 (2024), no. 4, 2841-2854)在量子纠错码背景下的延续。我们利用代数不变量理论研究形式自对偶量子码的三种重量枚举式。我们推导出量子格莱森定理的类比,证明形式自对偶量子码的重量枚举式可以由两个多项式代数表示。我们还表明形式自对偶量子码的双重重量枚举式可以由五个多项式代数表示。我们明确计算了某些特殊自对偶量子码的完整重量枚举式。我们的方法展示了运用代数不变量理论计算自对偶量子码重量枚举式的潜力。

英文摘要:

This article is a continuation of our recent work (Yin Chen and Runxuan Zhang, Shape enumerators of self-dual NRT codes over finite fields. SIAM J. Discrete Math. 38 (2024), no. 4, 2841-2854) in the setting of quantum error-correcting codes. We use algebraic invariant theory to study three weight enumerators of formally self-dual quantum codes over arbitrary finite fields. We derive a quantum analogue of Gleason's theorem, demonstrating that the weight enumerator of a formally self-dual quantum code can be expressed algebraically by two polynomials. We also show that the double weight enumerator of a formally self-dual quantum code can be expressed algebraically by five polynomials. We explicitly compute the complete weight enumerators of some special self-dual quantum codes. Our approach illustrates the potential of employing algebraic invariant theory to compute weight enumerators of self-dual quantum codes.
