 ### Added
 
+- ✨ Add a new QDMI device that represents a superconducting architecture featuring a coupling map ([#1328]) ([**@ystade**])
 - ✨ Add bi-directional iterator that traverses the def-use chain of a qubit value ([#1310]) ([**@MatthiasReumann**])
 - ✨ Add `OptionalDependencyTester` to lazily handle optional Python dependencies like Qiskit ([#1243]) ([**@marcelwa**], [**@burgholzer**])
 - ✨ Expose the QDMI job interface through FoMaC ([#1243]) ([**@marcelwa**], [**@burgholzer**])
