@CatalinaAlbornoz please can you help me. Danke 
Hi @Horacio ,
You’re not applying the correct gates. One very good way to debug is to print your circuit. Copy your code into a Jupyter Notebook in Google Colab, !pip install pennylane there, and draw your circuit with qml.draw_mpl(apply_hxh)(0).
Do you get the same circuit that you need to apply?
I hope this helps you!
