Thank you for the submission. Would you mind providing the qasm files for the circuit that produced these results? You can edit this same issue. At the bottom of the markdown raw text, there is a button that says "Paste, drop, or click to add files". You can create a .zip file from the qasm circuit and drop it there. Github will take care of unzipping the file.

Additionally, could you provide additional information about the specific instance of the Excitation-Preserving Ansatz used? I am assuming you are using the qiskit implementation, correct? If so, could you describe what are the arguments used in the function call? In particular: mod, entanglement, and reps.

Best regards,
Javier

Thank you for the review. @jrm874

First of all, we added the .zip file containing the qasm file for the quantum circuit that produced this result.

As you guessed, we used ExcitationPreserving from qiskit.circuit.library with mod = 'iswap' / entanglement = 'linear' / reps = 2. Other miscellaneous options were kept as their default values.

Best, Kyungmin
