What is the practical application of this then, considering that you can choose an arbitrarily large key to make eavesdropping or tampering practically impossible?

I don't get what's so exciting about this.

Or does this only become practically useful once quantum computing breaks traditional encryption?

From what I have gathered it is relatively easy to create protocols that are not insecure in presence of quantum computing.
