"What are the incentives of the authors ?" This is first question that needs to be asked of any "study" or "project" that attempts to address Quantum and BTC. If there is a token, a Series A, if the authors are paid by the Ethereum foundation, or if the authors have significant other investments in crypto other than Bitcoin, then we have to assume they are bad actors. The right way, and the only way to address Quantum and BTC is from the Bitcoin community itself. This is not a "cross chain" thing. What works for Solana is irrelevant for BTC. We need a pure Bitcoin approach to this. nic Carter and project eleven should be ignored and rejected at all costs, simply on the basis of conflicts of interest. Coinbase's "multi chain" effort as well.
