Not entirely correct, as I understand it. Granted, quantum computing will shred most (all?) of the ciphers we currently use. But that's mostly because they will be able to do massively efficient prime factorization using something like Shor's algorithm (https://en.wikipedia.org/wiki/Shor%27s_algorithm). If I understand correctly, resisting such technology doesn't require creating a cipher that takes a quantum computer to decrypt but one that is resistant to efficient factorization.
