Thanks for this very pedagogical video!

I would be curious to see more use cases for parametrized circuits. What are the operations that they support except for parameter substitution? (is it possible to do e.g., derivatives, circuit simplification, etc?)

Im trying to make a parameterized custom gate, which i made from a Unitary matrix containing the parameters. But everytime i try to make the circuit with the parameterized gates i get the error: ParameterExpression with unbound parameters ({Parameter(θ)}) cannot be cast to a float. What should i do to fix this?

Why Qiskit SDK modules so badly nested?

How can i design a neural network for a regression problem. The architecture proposed in all kinds of papers is just for classification problem. What if I want to do a regression problem with Quantum. Please help eith any RNN or LSTM architecture using Quantum

[wupeter]

if i want import two or three different parameter(eg. a, b, c ). so what should i do?
