Just as a small hint: you could actually adapt some of the MQT Core tests for dynamic circuits here.
Dynamic variants are available for BV, QFT, and QPE.

Additional side note: the Qiskit backends probably should add the Reset gate as a supported operation and should also be tested.
I'd suppose that not all of the backends support the operation though, e.g., the Simulation Path and the unitary simulator.

Good point, I'd do this as addition to or after #267 to avoid just creating conflicts in merging.

Agreed! 👍🏻 then this is good to go from my end!
I'll also work on extracting that reset functionality in MQT Core itself so that code duplication is minimized. It should be as simple as calling an applyReset function in the simulator.
