量子信息中的$\ell_{1}$ -范数

The $\ell_{1}$-norm in quantum information via the approach of Yang-Baxter Equation

Kai Niu, Kang Xue, Qing Zhao, Mo-Lin Ge

摘要:

利用Wigner D-函数研究了$\ell_{1}$ -范数在量子力学中的作用,其中当$\left|ψ_{i}\right\rangle $是单正交归一化基时,$\ell_{1}$ -范数表示对$\left|Ψ\right\rangle =\sum_{i}C_{i}\left|ψ_{i}\right\rangle $的$\sum_{i}\left|C_{i}\right|$.本文证明了目前两类作用于物理学自然基的变换矩阵是一个统一的辫子矩阵,它可以看作是Yang-Baxter方程(YBE)的特解。$\ell_{1}$ -范数的最大值与最大纠缠态和两分量任意子的拓扑量子场论(TQFT)有关,而最小值则与费米子或玻色子的排列有关。

英文摘要:

The role of $\ell_{1}$-norm in Quantum Mechanics (QM) has been studied through Wigner's D-functions where $\ell_{1}$-norm means $\sum_{i}\left|C_{i}\right|$ for $\left|Ψ\right\rangle =\sum_{i}C_{i}\left|ψ_{i}\right\rangle $ if $\left|ψ_{i}\right\rangle $ are uni-orthogonal and normalized basis. It was shown that the present two types of transformation matrix acting on the natural basis in physics consist in an unified braiding matrix, which can be viewed as a particular solution of the Yang-Baxter equation (YBE). The maximum of the $\ell_{1}$-norm is connected with the maximally entangled states and topological quantum field theory (TQFT) with two-component anyons while the minimum leads to the permutation for fermions or bosons.
