稳定子码的有效哈密顿量的界

Bounds on Effective Hamiltonians for Stabilizer Codes

Stephen S. Bullock, Dianne P. O'Leary

摘要:

这份手稿介绍了各种概念的k-局部性的稳定器代码继承相关的稳定器组。群的生成元的选择导致一个在其基空间中具有码的哈密顿算子,而一个在其基空间中具有码的哈密顿算子可以被称为有效的,如果它的局部性小于生成元的自然选择(或任何选择)的局部性。本文建立了稳定子码不存在有效哈密顿量的条件。我们的研究结果简化的情况下,Calderbank-Shor-Steane稳定器代码和拓扑有序的稳定器代码所产生的表面cellulations。

英文摘要:

This manuscript introduces various notions of k-locality of stabilizer codes inherited from the associated stabilizer groups. A choice of generators for the group leads to a Hamiltonian with the code in its groundspace, while a Hamiltonian holding the code in its groundspace might be called effective if its locality is less than that of a natural choice of generators (or any choice). This paper establishes some conditions under which effective Hamiltonians for stabilizer codes do not exist. Our results simplify in the cases of Calderbank-Shor-Steane stabilizer codes and topologically-ordered stabilizer codes arising from surface cellulations.
