Process tomography for the two-qubit entangling gate. a Real component of the measured process matrix. b Imaginary component of the measured process matrix. c Real component of the ideal process matrix. d Imaginary component of the ideal process matrix. e Gate fidelity of the measured process matrix and most-likely completely positive process matrix and two-qubit Bell state fidelity as a function of interaction strength. Error bars are statistical errors
