Unless you move to another family of algorithms based on information-theoretic limits on what an eavesdropper can know. Some methods I remember involve neural networks in the form of tree parity machines with a hidden layer (mutual learning is provably faster than learn-by-watching), others use noisy channels (say readings from a distant radio-source in deep space), others put a limit on the amount of data an attacker could store...
All those have in common is that they require quite large data transfers (so they're quite impractical) and the success probability of an attack is mathematically limited (though quite "high" compared to current PK and SK crypto, but can be made as small as you like by iterating enough times). *No* advance in computing power can break 'em, unless it makes a brute-force attack possible. If the problem is "just" the birth of quantum computers, then there already are some practical algorithms that address the issue (NTRU and McEliece, as already pointed out by others).
