"I was going to ask you to explain quantum computing," he said, as the crowd chuckled with delight. The reporter then tried to move on, asking something serious about how Canada is dealing with terrorism, but Trudeau saw an opportunity to answer a way more fun question for a change. He launched into the explanation about computing, drawing applause from the crowd. "No, no, don't interrupt me," the prime minister said over the claps. "When you walk out of here, you will know more — no, some of you will know far less about quantum computing — but most of you."

Trudeau then explained how normal computers are binary systems. "There's either power going through a wire or not. It's either 1 or a 0," he explained. "What quantum states allow is for more complex information to be encoded into a single bit." I mean, that all sounds legit to me, but I'll be honest, my quantum computing knowledge could use some refreshing. I shouldn't just assume that Trudeau knows what he's talking about. So I consulted our very own Russell Brandom about how quantum computing works.

Yeah, so Trudeau knows his physics.
