Re:Quantum Computer Comes Closer to Cracking RSA Encryption

There are not, not in OpenSSL. Viable post-quantum encryption is a hot research area right now. There are a number of approaches that seem promising; some of them, like hash-based, lattice-based, and code-based crypto, are actually relatively old concepts that were pushed aside because RSA is more efficient, but which regain their edge if quantum computers become viable.
The trick with all of this is that there isn't all that much cryptanalysis work of some of the more promising PQ schemes, so trying to preemptively adopt them just in case quantum computers learn to factor numbers bigger than 15 is likely to do more harm, in the short term, than good.
