Web23 hours ago · GramSchmidt 模块是用于计算正交向量组的 Python 模块。 它的作用是将一组线性无关的向量转换为一组正交的向量,以便更方便地进行计算。该模块的实现基于 Gram-Schmidt 正交化算法,可以通过调用 scipy.linalg.orth 函数来实现。 在使用该模块时,需要注意输入向量组必须是线性无关的,否则会出现计算错误。 WebMay 15, 2009 · It is shown that the Hilbert-Schmidt (HS) norm and distance, unlike the trace norm and distance, are generally not contractive for open quantum systems under Lindblad dynamics. Necessary and sufficient conditions for contractivity of the HS norm and distance are given, and explicit criteria in terms of the Lindblad operators are derived.

WebDec 1, 2024 · The Hilbert schmidt norm is $ A ^2_ {HS}=\sum Ae_i ^2_H$ where $ {e_i}$ is an orthonormal basis on the Hilbert Space. I have shown the norm is independent of the choice of basis. – Bill Dec 1, 2024 at 14:56 Great, now if $B$ is bounded, you can estimate $$\Vert BAe_i\Vert_H\leq \Vert B\Vert_H \Vert Ae_i\Vert_H$$ and we are in business.
