The errors have been calculated assuming the statistical independence of the variables summed: therefore, the variances have been added and then the square root was taken to obtain the standard deviation of the sum.

  ABSTRACT: The 5-qubit quantum computer prototypes that IBM has given open access to on the cloud allow the implementation of real experiments on a quantum processor. We present the results obtained in five experimental tests performed on these computers: dense coding, quantum Fourier transforms, Bell’s inequality, Mermin’s inequalities (up to n=5) and the construction of the prime state . These results serve to assess the functioning of the IBM 5Q chips.
