Meyer-Wallach measure

How can we correctly implement the standard Meyer-Wallach measure using PennyLane? We’ve been encountering difficulties in accurately calculating the final Q value. Would it be possible to provide a reference implementation of the standard Meyer-Wallach measure for guidance? Thank you. For your reference, the Meyer-Wallach measure is detailed in the following paper: https://arxiv.org/pdf/quant-ph/0305094.pdf.

Hey @zj-lucky!

I’m not aware of any implementations of this measure that you can reference. Maybe I can still give you a hand, though. Can you be a bit more specific / detailed here? Seeing some code would help alongside a specific equation(s) from the paper you attached.
