Well not RSA, that will be broken by quantum computers. But there are some classical encryption methods that quantum computers are not known to break.
Do you want pre-shared secrets and the expense of a quantum network to, in theory, have infinite security (in theory!), or are you okay with tried and tested RSA which gives you >1000000000 years security at a much cheaper cost, that actually works in practice?
