What about building quantum safe protocols? Is that as a field any more interesting and/or viable?

Yes. Plenty of stuff happening in that field.

The challenge is: Right now we can choose between probably safe, but impractical (mcbits, sphincs) and practical, but with big questionmarks about how safe they are (newhope, sidh). The problem is: We really only trust crypto algos if they have been tested and researched over a long time, but lots of these things are pretty new.

That's called post-quantum cryptography, not quantum cryptography.

As I understand it, "quantum safe" and "post-quantum" describe the same thing.

I never used the term 'quantum cryptography'

I think I meant to respond to the parent comment, not yours. But that was hours ago.
