What are the post quantum cryptography protocols that have been proposed until now?
I know about McEliece cryptosystem, and LWE scheme. What are the others? Can you provide me a list or a website containing such list?

First, a pedantic point: be careful with terminology: there currently are no Post-Quantum "protocols" (TLS, S/MIME, CMP, etc). From your question, I'm assuming you are interested in PQ "schemes", or PQ "primitives" (XMSS, R-LWE, etc). This may seem like nit-picking, but we can expect NIST to standardize primitives in the next 3 - 5 years, protocols will take longer than that!
Now for your actual question. As @SEJPM points out, the research is still very young and is rapidly changing, so any links to actual schemes will very quickly go out of date. What I will do instead is link to the organizations that you should be following.
firstname.lastname@example.org the mail-list for discussion of post-quantum schemes and their standardization. This went live very recently so I can't find any references to it online, but you can get yourself onto it by sending an empty email to
This is probably fairly thorough.. http://csrc.nist.gov/publications/drafts/nistir-8105/nistir_8105_draft.pdf
In public key cryptography,three schemes are quantum-secure:
and in symmetric encryption like AES,if you choose a long key;you are safe against quantum computer and NSA!
