List of post quantum cryptography protocols 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out, the research is still very young and is rapidly changing, so any links to actual schemes will very quickly go out of date.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.

NIST


Link to their talk from the recent PQCrypto2016 conference outlining their upcoming call for applications for candidate PQ signature and encryption schemes.
See their February 2016 report, basically a "What we know at this point".
pqc-forum@nist.gov is 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 pqc-forum-request@nist.gov with subject:subscribe


NSA


See their Suite B page (at time of writing, it was last updated in August 2015).
See their January 2016 announcement of the replacement of Suite B.


PQCrypto Project


Group funded by the European Union to research and recommend PQ schemes.

IETF / IRTF's Crypto Forum Research Group (CFRG)


Draft standard for XMSS hash-based signatures.
