System and method for routing signals in complex quantum systems

A quantum computer system comprising:

• a plurality of quantum circuits arranged in a two-dimensional layout;
• and
• wherein the plurality of quantum circuits includes at least one interior quantum circuit that is not along a perimeter of the two-dimensional layout, wherein the at least one interior quantum circuit comprises a plurality of layers, a top layer of the plurality of layers including a through hole to a bottom layer of the plurality of layers;
• and
• a signal wire positioned at least partially within the through hole and connecting the bottom layer to the top layer.

A quantum computer system comprising:

• a plurality of quantum circuits arranged in a two-dimensional layout, the plurality of quantum circuits including at least one interior quantum circuit that is not along a perimeter of the two-dimensional layout, wherein the at least one interior quantum circuit includes a device layer and a routing layer;
• a signal wire that connects the device layer to the routing layer, wherein the signal wire extends out of the two-dimensional layout of the plurality of quantum circuits;
• and
• a through hole formed in the routing layer, wherein the signal wire pass though the through hole.
