EVENTO
Analyzing Toffoli Gate in Disordered Circuit QED
Tipo de evento: Seminário de Avaliação - Série A
We study the effects of imperfections on the fidelity of the Toffoli gate recently realized in acircuit QED setup using quantum control methods. The noise is introduced in the interqubits interactions. The coupling constants are no longer fixed, instead, they fluctuate around average values obeying some given probability density functions characterizing the dynamical-imperfection case. We also consider the static-imperfection case in which the values of the coupling constants are not exactly known. We obtain a more robust gate by modifying the quantum optimization problem using a weighted average of the fidelity over an interval of coupling values as the objective functional.
