Bell State Preparation
The prepare_bell_state function creates one of the four Bell states
\[\phi_{+} = \frac{1}{2} \left(|00\rangle + |11\rangle \right)\]
\[\phi_{-} = \frac{1}{2} \left(|00\rangle - |11\rangle \right)\]
\[\psi_{+} = \frac{1}{2} \left(|01\rangle + |10\rangle \right)\]
\[\psi_{-} = \frac{1}{2} \left(|01\rangle - |10\rangle \right)\]
Function: prepare_bell_state
Arguments:
-
state_num: CInt -
q: Output[QArray[QBit]]
Example
The prepare_bell_state function creates
\[\psi_{+} = \frac{1}{2} \left(|01\rangle + |10\rangle \right)\]
state_num is set to 2
