is it a good idea to invest in post-quantum cryptography or is it too risky/early?

​

investing in quantum computer stocks is already a risk, but i'm wondering if stocks like microchip technology (MCHP) or lattice semiconductor (LSCC) is a good idea? my thoughts are that even if quantum doesn't take off like predictions suggest, the cryptography is already mandated by governments and would be necessary even if only a few quantum computers are created.
