&gt;&gt;Wind tunnel tests could be a thing of the past thanks to quantum computing<p>What a  bunch of bullocks! How the heck do you verify that your simulator is doing something useful or physical?<p>For example, the non-linear-Schrodinger equation can be used to approximate transmission through a fiber optic but in the derivation there is a paraxial approximation. Is this valid? Equally, Maxwell&#x27;s equations are usually written for perfectly coherent fields, is this valid for the problem at hand?
