The Parameter-Shift Rule
------------------------

In the quantum case, the expectation value of a circuit with respect to an measurement operator
In the quantum case, the expectation value of a circuit with respect to a measurement operator
:math:`\hat{C}` depends smoothly on the the circuit's gate parameters :math:`\theta.` We can write this
expectation value as :math:`\langle \hat{C}(\theta)\rangle.` This means that the derivatives
:math:`\nabla_\theta \langle \hat{C} \rangle` exist and gradient descent can be used.
