TL;DR, until the core protocol is changed, it would only be safe to use a public address once, as using it more than once can lead to the discovery of your private address. Will also have major implications on password security, high frequency trading, etc. Don't worry though, prob many decades away.

This was addressed by the core development team (Andreason?) a while back. Apparently it's pretty easy to switch things over to a new security protocol. It would require a hard fork obviously but it shouldn't be to difficult to coordinate an "upgrade day."

Yes, jus like dealing with 51% attack...easy....just little bit of hard forking..."we'r gonna fix it once it happens"

there will be a patch to protect against quantum tech
like make each transaction use new addresses instead of reusing previously used addresses to guard against quantum attacks
change in the encryption protocols to guard against quantum
