\section{Another sample section}
\label{sec:sample}

Here is a sample equation:
\begin{equation}
  X = \begin{pmatrix} 0 & 1 \\ 1 & 0 \end{pmatrix}
\label{eq:sigmax}
\end{equation}
We can now refer to this as \eq{sigmax}.

Aligned equations can be produced as follows:
\begin{align}
  \ket{\beta_{00}} &= \frac{1}{\sqrt2} (\ket{00}+\ket{11}) \\
  \ket{\beta_{01}} &= \frac{1}{\sqrt2} (\ket{01}+\ket{10}) \\
  \ket{\beta_{10}} &= \frac{1}{\sqrt2} (\ket{00}-\ket{11}) \\
  \ket{\beta_{11}} &= \frac{1}{\sqrt2} (\ket{01}-\ket{10}).
\end{align}
