We use the different quantum computers which IBM made available on the cloud (IBM Q Experience) to implement different quantum circuits. First, we study the dynamics of a single spin interacting with a magnetic field using the main single-qubit gates, which allows us to obtain the evolution of the three components of the spin. Finally, we study the performance of the quantum computers by implementing two quantum algorithms: the dense coding protocol, which we use to study the connectivity between qubits, and the quantum Fourier transform, which we use to study the performance of three different quantum computers when the number of qubits is increased.
