I can not extract the final statevector when using a binded Parametric Controlled gate
I'm trying to implement a Parametric Hadamard Test.
I have already my parametric evolution gate $\exp(-i\theta H)$ where $\theta$ is the parameter.
When I defined the controlled-gate with Gate.control(...

How to get rid of the indices of qubits at the side of a custom gate when visualizing a circuit (IBM Qiskit)
I have written a function that applies the Hadamard gate to all qubits in a circuit, and use the draw() function to visualize the circuit. However, there is this ...

Represent the $n$-qubit $2^n\times2^n$ size Hadamard/quantum Fourier transform unitary square matrix as product of $k$ two-level unitary matrices
I wish to know if it is possible to express the n-qubit Hadamard unitary square matrix of size $2^n * 2^n$ as a product of 'k' two-level unitary square matrices where 'k' is of the order of polynomial ...
