Q: There seems to be a problem with the implementation of identity gates on Qiskit as compared to the circuit composer

JonasI have been experimenting with slowing down the decay of qubits, and as a control, I implemented a circuit with just identity gates for comparison. However, when I implement such circuits in Qiskit, no matter how many identity gates I put, I get about the same fidelity each time. For example, I i...

Q: What is the intuition of using Hadamard gate in quantant fourier transform?

user3176354According to this answer by rrtucci , I still cannot catch the spirit of QFT algorithm. So I would like to ask why we are using Hadamard Gate when computing Fourier Transform? Moreover, what is the main idea behind Hadamard Gate? Thank you!
