Paper Abstract

The present work analyses the effect of T1 and T2 relaxation on the fidelity of quantum gates in terms of Choi-Jamiolkowski isomorphism. Numerical computations is used to show that the value of fidelity is nearly independent of the gate Hamiltonian. This fact leads to the universal estimate of fidelity, and the accuracy of this estimate is studied, especially for the case of one qubit.
