Key Equations

$$\hat{A}(\alpha|\psi\rangle + \beta|\phi\rangle) = \alpha\hat{A}|\psi\rangle + \beta\hat{A}|\phi\rangle$$
$$\langle \psi | \hat{A}^\dagger | \phi \rangle = \langle \phi | \hat{A} | \psi \rangle^*$$
$$\hat{A}^\dagger = \hat{A}$$
$$\langle a | \hat{A} | a \rangle = \langle a | \hat{A} | a \rangle^*$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
