Post-quantum projects?

Recently read both Google and Binance papers about quantum computers effect on blockchains. Definitely sounds like something we should be taking seriously. The Google paper cites some projects that are either already quantum-safe or actively working on it. Anyone know of solid post-quantum cryptography projects worth investing in? With quantum computing advancing fast, I want to hedge my portfolio with something built to survive that shift. I’ve seen a few names floating around but curious what the community thinks. Are there any projects that actually have strong fundamentals around?
