Sure, and we here on Slashdot are criticising the silly article. And I'm criticising your silly repeating of the silly claim that polarization is not a quantum phenomenon because you can "explain" it (in a very narrow energy range if you squint and don't look too close) using classical physics. I probably wouldn't have replied at all if you hadn't told one of your other replies "it's okay if you don't understand quantum mechanics."
The actual paper doesn't use "first quantum material" at all. It says "first class of room-temperature quantum materials that are intrinsically sensitive to the quantum statistical properties defining all forms of light". They actually write it all out twice, which suggests to me that they were aware that shortening it to "quantum material" would sound ridiculous.
In fact, on casual reading it appears to be a fancy polarizing filter that's also sensitive to coherence.
