You're probably thinking of safety of symmetric encryption, where there is a quadratic speedup from quantum computers. https://en.wikipedia.org/wiki/Grover's_algorithm The situation is a lot worse with public-key encryption, where there is a much bigger speedup https://en.wikipedia.org/wiki/Shor%27s_algorithm So experts generally believe that we don't really need new symmetric encryption algorithms to defend against quantum computers (things like AES are OK), but we do need new public-key algorithms (things like RSA are not OK).
