How to use qml.SpecialUnitary as a unitary and makes its evolution through a given density matrix

[SUDHIR_KUMAR_SAHOO]

I have a denisity matrix of which is corrupted by depolarizing noise and I want to add some ancilla and take this density matrix evolve through quantum evolution via qml.SpecialUnitary(). How ever I can not able to perform evolution. Please help in this reagrds.

Hey @SUDHIR_KUMAR_SAHOO,

Have you checked out our demo on this? Here comes the SU(N): multivariate quantum gates and gradients | PennyLane Demos

That’s a great place to start! Let me know if that helps

Thanks @isaacdevlugt Just yesterday I had found the demos in this regards. Thanks a bunch.
