In this talk, we extend these protocols for control of multiple cavity modes weakly coupled to an ancilla qubit. In this multimode context, these gates increase the contrast between the rates of gate operations with the target modes, and those of spurious coherent errors from photons in non-target modes. We present multimode generalizations of echoed-conditional displacements sequences–entangling multiple cavity modes with sequential conditional displacements of the individual modes. We also produce multimode gates from related pulses generated by numerical optimization via GRAPE. Our work presents a pathway for potentially implementing cross-talk resilient multimode processors that are also more immune to ancilla errors.
