Relations between single and repeated qubit gates: coherent error amplification for high-fidelity quantum-gate tomography

In quantum computation the target fidelity of the qubit gates is very high, with the admissible error being in the range from 10 ^−3 to 10 ^−4 and even less, depending on the protocol. The direct experimental determination of such a tiny error is very challenging by standard quantum-process tomograp...
