Trudeau was announcing a new $50 million infusion of federal funding for STEM programs. He took the microphone when one reporter posed a facetious challenge to Trudeau’s computing know-how, joking, “I was gonna ask you to explain quantum computing, but...” before launching into his policy query.
Trudeau's explanation of quantum computing
Normal computers work, either there’s one power going through a wire or not. It’s one or a zero, they’re binary systems. What quantum states allow for is much more complex information to be encoded into a single bit. Regular computer bit is either a one or a zero, on or off. A quantum state could be much more complex than that, because, as we know, things could be both particle and wave at the same time, and the uncertainty around quantum states allows us to encode more information into a much smaller computer. So that’s what’s exciting about quantum computing.
