In the case of the Hadamard gate, the most probable result is 50% each, but results close to 50% have non-negligible probabilitie and frequently occur. To obtain results closer to 50%, we have to increase the number of shots. If we choose to run on a quantum computer, the circuit will be queued and may take a long time. We can check the size of the queue when we are selecting the system. The output of the quantum computer is usually different from the simulator because errors degrade the result Increasing the number of shots doesn’t guarantee that the probability distribution tends towards the correct distribution, and it is important to check the correctness of the circuit through th simulator before running on the quantum system.
