I am using Qiskit to run some circuits and a question arises in my mind. I know that when we run in the simulators we are running in "ideal" environments. This means there is no noise that could cause errors in the readouts. So I expect this to be reflected in the expected results.
But when I run a circuit for example, the running time on a real machine is much bigger than in a simulator.
So my question is: why is it faster to run programs or circuits on a simulator? Is the noise of the real device affecting the speed of the computations?
Thank you very much in advance!
