Re: LUKS and quantum computing

[Arno Wagner <wagner@arnowagner.info>]

No idea. And frankly, I have stopped caring. "Quantum Computing" is
a Fata Morgana that does not amount to anything practical at this 
time (after 50 years of resarch) and may well never amount to anything.  
It will certainly not be a real treat in the foreseeable future.

Here is what Peter Gitman thinks of the topic, and I think it
is spot on: https://www.cs.auckland.ac.nz/~pgut001/pubs/bollocks.pdf
