You likely mean the nist post quantum competition, which is about public key encryption and signatures.

The answer is noone yet, it's still running. Here's the list of proposals currently in the competition: https://csrc.nist.gov/Projects/post-quantum-cryptography/rou...

These are symmetric ciphers. So.. All of them?

One thing though is that many lightweight block ciphers only have 128 bit keys. So in a PQ context, they will only provide 64 bit strength. Thus might be ok for short term secrets. But if you are building devices (IoT, SCADA) with long lifetimes, you may need to add a key derivation, key exchange scheme.
