It was a coherent summary of a complex subject, delivered clearly, with just enough information to support the point of his message without getting bogged down in details. This takes skill; popular science writers make their livings and sometimes even become famous based on their ability to create this kind of summary.

Whether or not Trudeau's knowledge of the topic goes any deeper than what he's said here, he's demonstrated that he either cares enough about the subject to have consulted with people who understand it and learned how to repeat their explanations without falling off the rails, unlike good ol' Senator Ted "Series of Tubes" Stevens for example, or that he cares about the subject enough to have learned enough about it that he can articulate an opinion in a clear and accessible way. Either way, what's impressive is not that he is repeating information which is true, but that he cares enough about quantum computing to get it right.
