1. A device, comprising:
a qubit layout comprising a plurality of repeated and connected unit cells, and the plurality of repeated and connected unit cells comprising individual sets of qubits; and
the plurality of repeated and connected unit cells comprising different cross talk groups of qubits having qubit islands connected together by couplers in different orders, wherein the different cross talk groups are repeated among the plurality of repeated and connected unit cells of the qubit layout, wherein the plurality of repeated and connected unit cells comprise first cross talk groups and second cross talk groups, and wherein the first cross talk groups are operable with greater cross talk than the second cross talk groups.
