  We have implemented the six series of three commuting measurement of the
Mermin-Peres magic square on an online, five qubit, quantum computer. The magic
square tests if the measurements of the system can be described by physical
realism (in the EPR sense) and simultaneously are non-contextual. We find that
our measurement results violate any realistic and non-contextual model by
almost 28 standard deviations. We also find that although the quantum computer
we used for the measurements leaves much to be desired in producing accurate
and reproducible results, the simplicity, the ease of re-running the
measurement programs, and the user friendliness compensates for this fact.
