Cardano was mentioned 5 times (plus 3 citations) on the Google Quantum AI whitepaper. And it was ranked in the second-best tier for quantum resistance, right behind purpose-built quantum-proof chains. Above Ethereum. Above Solana. Above XRP. The UTXO architecture gives Cardano a structural advantage that account-model chains don’t have. So Google essentially said your spending keys can be protected on Cardano.(Dan Gambardello)
