Bell State Preparation

The BellStatePreparation function creates one of the four Bell states

\[ \phi_{+} = \frac{1}{2} \left(|00\rangle + |11\rangle \right) \]

\[ \phi_{-} = \frac{1}{2} \left(|00\rangle - |11\rangle \right) \]

\[ \psi_{+} = \frac{1}{2} \left(|01\rangle + |10\rangle \right) \]

\[ \psi_{-} = \frac{1}{2} \left(|01\rangle - |10\rangle \right) \]
