Everyone Should Be Able To Explain Quantum Computing Like Justin Trudeau

When Canadian Prime Minister Justin Trudeau schooled a journalist on the basics of quantum computing yesterday, I was initially as charmed and delighted as everyone else. But then a niggling sense of dismay set in. Why should this be such a singular newsworthy event? How come so few of us can do what Trudeau did, when science plays such a central role in almost every aspect of our daily lives?

Trudeau made the remarks during a press briefing at the Perimeter Institute in Waterloo, Ontario, announcing $50 million in funding to continue its world-class cutting-edge research in fundamental physics—including quantum information, a theoretical cornerstone of quantum computing. (Perimeter is one of a handful of institutions that make up Canada’s “Quantum Valley.”) A journalist in the audience jokingly said, “I was going to ask you to explain quantum computing, but.... haha...” The subtext: We are all too dumb to really grasp this esoteric thing—that is only for really smart people with PhDs.


The Prime Minister didn’t join in the hilarity. Instead, he brought down the house with this little spiel:

As off-the-cuff explanations go, this is remarkably clear and concise, outlining the bare minimum of facts without getting too deep into the weeds—in other words, it was pitched perfectly for a general audience. But the swooning response also reveals just how little we expect of our political leaders when it comes to basic scientific literacy. And we expect even less from ourselves. As physicist Jon Butterworth observed in The Guardian this morning:

It is the kind of thing any sufficiently engaged politician could pick up from a decent briefing, given expert help. Such help is available in abundance at Perimeter, and available anywhere to any suitably senior politician who wants it. Kudos to Trudeau for being clever, interested and confident enough to do this. [Emphasis mine.]


That’s the source of my dismay, because every single one of us has ready access to this kind of information, 24/7, on this glorious thing we call the internet. There are news articles, explainers, videos, and online games and tutorials. Yet the vast majority of the population can’t be bothered, avoiding most science like the plague —hard sciences like physics and math in particular.

We don’t need to understand every last technical nuance, but quantum mechanics has been around for nearly a century now. It’s behind every single piece of modern technology that we now take for granted. Is there really any excuse not to know that light and matter have both particle and wave aspects; that the more you know about a particle’s position, the less you know about its momentum (a.k.a. the Uncertainty Principle); or the alive-and-dead superposition of states at the heart of the Schroedinger’s Cat paradox? And we should certainly know the basics of how our computers work.

Earlier this year, Gizmodo featured a fantastic video of actor Paul Rudd doggedly taking on Stephen Hawking in a game of quantum chess, with a little help from Keanu Reeves, texting from the year 2716. The underlying message: “Anyone can quantum!” It’s not just for really smart people with PhDs.

Our tagline at Gizmodo is “We Come From the Future.” Well, my vision of the future is one where basic scientific literacy is not the exception, but the norm. Justin Trudeau’s impromptu response is a perfect example of what that future could look like. Let’s all do our part to make it happen.
