inner_product

forest.benchmarking.operator_tools.calculational.inner_product(bra1: numpy.ndarray, bra2: numpy.ndarray) → complex

Given two possibly complex row vectors bra1 and bra2 construct the inner product:

<bra1|bra2>

which can be complex,

Parameters:

• bra1 – Is a dim by 1 np.ndarray.
• bra2 – Is a dim by 1 np.ndarray.

Returns:

the inner product.
