12# # Routing with Airbridges Example 

13# 

14# This example demonstrates how to use airbridges in quantum circuit routing to prevent slot mode propagation and reduce crosstalk between transmission lines.

24# Creates two launcher components and routes between them using coplanar waveguides with airbridges.
