IBM Quantum Experience - First Looks

1. Run on a simulator of an ideal quantum processor. Ideal means there would be no decoherence errors.

2. Run on a simulator of a real quantum processor.  This realistic simulation would take into account a probabilistic model of what errors may occur to decoherence.

3. Run the score on the actual quantum processor that IBM has put on the web. Since there may be multiple users who are doing this or the processor may be unavailable for temporary maintenance, IBM will queue up the requests and run these in a batch mode.    After your job is done IBM will store the results in the data base and send you an email notifying you that the job has completed. There is no limit to the number of simulator runs allowed.   However, IBM does ration the number of runs on the actual processor with a system of processing units that they will periodically provide you. You can view the results section to see the final output.   Depending upon what type of measurement block you put at the end, it will show you a bar chart showing the probabilities of each end state or it will show you a Bloch sphere that will show the complete state of the qubit in three dimensions.
