  <description>いわゆる $A = U \Sigma V^{*}$ な特異値分解を簡単なケースで眺めてみたい。2 乗するち単位行列になるという扱いやすい性質を持つ Pauli 行列を少し改造して$$ \begin{align*} A = \begin{pmatrix} 0 &amp; -\frac{i}{2} \\ \frac{i}{3} &amp; 0 \end{pmatrix} \end{align*} $$を考えたい。これは$$ \begin{align*} A^{*} A = \begin{pmatrix} \frac{1}{9} &amp; 0 \\ 0 &amp; \frac{1}{4} \end{pmatrix} \end{a…</description>
