Hello everyone.
I want to estimate the execution time of some experiments, and I would be interested to know how the time needed to run a quantum circuit grows in function of the number of qubits and the parametric gates. I am interested in both real quantum hardware and simulators.
In the case of simulators, I guess that it will grow exponentially with the number of qubits, but it is not clear to me how it will grow with parametric gates (and if it will take longer with certain gates).
I would appreciate any information you can give me or any paper you can recommend.
Thank you very much
Hey @barrieta005! Welcome to the forum! 
It’s a little out of date — especially for PennyLane’s results — but this paper comes to mind (compares all sorts of quantum programming software packages very rigorously): https://arxiv.org/pdf/1912.10877.pdf
You can find some code for it here: GitHub - yardstiq/quantum-benchmarks: benchmarking quantum circuit emulators for your daily research usage
For PennyLane-only benchmarks, usually we post insights into our performance enhancements on our blog. You can see some recent data here:
Let me know if this helps!
Thank you very much @isaacdevlugt !
Even though it is quite old, the article has clarified a few things for me
