Have you ever checked QRL at crypto51.app to know the theoretical cost of 51 attack? It costs 10$ per hour. Don't you think it's a bit ridiculous to talk about quantum computing with such a huge risk of simple 51% attack? 
There was a point at this matter on their discord, the hashrate calculation on crypto51.app is wrong and they have been notified by the QRL team itself. you can easily check it by looking at total networks hashrate in pool's view and the available hashrate on NH for CNV7, which is QRL running upon until PoS will kicks in.
Mining algo/hashrate/51%attacks have nothing to do with quantum resilience
