We're not done with non-quantum crypto yet.
- There is significant recent progress in performant and
side-channel resistant elliptic curves by D.J. Bernstein et. al.
- There is significant recent progress on RC4 cryptanalysis.
- The sponge construction in Keccac is a novel new building block.
- We're starting to move away from CBC mode to AEAD modes.
- Poly1305 is an interesting new MAC.
There is also active research on "post-quantum" cryptography, that
is asymmetric cryptography that resists both classical and quantum
algorithms.
I would ignore QKD, which is interesting Physics, but otherwise
largely marketing hype.

If/when practical and scalable QC is available, then we lose most
of the currently deployed asymmetric algorithms for signature and
key exchange. Thus the interest in post-quantum crypto.
However, classical crypto is by no means all done yet.
