- Abstract: The problem of finding efficient decompositions of multi-qubit gates is of
importance for quantum computing, especially, in application to existing noisy
intermediate-scale quantum devices, whose resources are substantially limited.
Here we propose a decomposition scheme for a generalized $N$-qubit Toffoli gate
with the use of $2N-3$ two-qutrit gates for arbitrary connectivity. The fixed
number of the required additional levels (the choice of qutrits is optimal) and
the use of the iSWAP gate as a native operation make our approach directly
applicable for ongoing experiments with superconducting quantum processors.
Specifically, we present a blueprint of the realization of the proposed scheme
for the Aspen-9 processor supporting quantum operations with qutrits.
