Whatever kind of proof you want, the request probably is a rhetorical stratagem and impossible to furnish.
Dictionary.com gives a long list of definitions of the word "proof". These are the most relevant ones:
(1) Evidence sufficient to establish a thing as true, or to produce belief in its truth.
(2) Anything serving as such evidence.
(3) The act of testing or making trial of anything; test; trial: to put a thing to the proof.
(4) The establishment of the truth of anything; demonstration.
(5) In mathematics and logic a sequence of steps, statements, or demonstrations that leads to a valid conclusion.
Is the kind of proof you want the mathematics and logic kind, (5)? I invite you to prove your own proposition in this way. That is, prove in this way your own proposition that qualia are material. It's a form of proof that isn't applicable to the subject.
Going back to science and its methodology, the proposition that qualia are not material has a large body of evidence, alluded to earlier. This consists of things like the demonstration of fundamental existential differences between the elements of qualia and the elements of material things. The one category of "things" is measured in fundamentally different units than the other. What evidence can you furnish that qualia are indeed material? It's a matter of the preponderance of evidence.
I want a logical proof, since all the claims that qualia cannot be a physical process are of the form "claims that qualia are a physical process make a category error" and such like. You just said they have "fundamental existential differences." That's a logical claim. If logical proofs are not applicable, then neither are the logical arguments against qualia being physical.
You are correct that probably no one can furnish a proof one way or the other. That is why I await further scientific study.
