How soon can the current crypto-protection system be replaced?

Question

Cryptography

Recently, the yellow press, citing Intel, announced a breakthrough in the field of quantum computers. Let's leave aside the reasoning that this is another duck from the category of "scientist raped a journalist." Let's say that already tomorrow (let's say early/mid 2018) there will be operating systems that can crack RSA, ECC and other asynchronous cryptography systems (and since we're making assumptions, let's not let them be sky-high expensive). How quickly will the world economy be able to adapt to new conditions (we are interested in the order of weeks / months / years), and in general, what is it supposed to replace modern cryptography with?

Answer 1

The world economy will rebuild EARLIER than such systems, because as soon as the first real sample is ready to go into mass production, information about this will already seep into place and the teams for the development of all programming languages ​​will quickly add features to languages ​​​​to protect the new order.
Banks rule the world and their protection is built, incl. on cryptography, it is simply not profitable for anyone to release a new computer that will bring chaos to the world's financial systems.
So the answer to your question is this: the current crypto-protection system will be replaced BEFORE devices that can break it enter the market.
Of course, there will be slowpacks that will not be updated, but this is the case with any vulnerabilities and these are already their problems.

Answer 2

Sifer will add a new one to SSL and that's it.
It is possible that even "cloudy" (if the current capacity can not cope).
First, they will prepare everything, and then they will revoke obsolete certificates (which will need to be re-issued / exchanged in advance for new ones) and you will need to ALREADY have working new ones.
So it's pointless to catch this interval.
