How secure will our data be in the post-quantum era?

It’s the end of modern cryptography as we know it, and we feel fine. Build your security for the next 50 years. If the speed of processing doubles every two years, make sure your cryptographic systems can’t be brute forced in 50 years. If you use 2048 bit RSA, it will take some quadrillion years to break it. Good enough, right? Quantum computing is about to throw that all on its head, ...
