You can just call it second stabilizer Rényi entropy or non-stabilizerness if you find "magic" strange and prose is more your flavor than poetry.

Strange quarks[1] are not magic. :)

Actually "non-stabilizerness" does describe it better than "magic".
> In quantum information theory, magic is a property that quantifies the computational resources needed to describe quantum states beyond stabilizer states.
> In 2024–2025, quantum magic was detected in top quark pairs produced at the Large Hadron Collider; it is the first observation of this property in fundamental particle collisions.

And "second stabilizer Rényi entropy" is even better, it's exactly the kind of technical term I'd prefer, that describes what it means.
> One measure of quantum magic is the stabilizer Rényi entropy of order α such that..
