In a recent press conference Justin Trudeau answered a journalist who asked him (initially jokingly) to explain quantum computers. He obliged with a <1 minute explanation which seems to receive acclaim across the social media.
Here's a video I found in YouTube: Canadian Prime Minister Justin Trudeau Explains Quantum Computing and here's a transcript (from this website):
.. normal computers work, either there’s power going through a wire, or not. It’s 1, or a 0, they’re binary systems. Uh, what quantum states allow for is much more complex information to be encoded into a single bit. Regular computer bit is either a 1 or a 0, on or off. A quantum state can be much more complex than that, because as we know [speeding up dramatically] things can be both particle and wave at the same times and the uncertainty around quantum states [laughter] allows us to encode more information into a much smaller computer. So, that’s what exciting about quantum computing ..
Is this explanation accurate? I realize it's a short one and probably simplifies a lot of things, but is the main assertion, like (1) wave-particle duality and "uncertainty around quantum states" is what enables more packed encoding? Or (2) encoding more information into a smaller computer is what quantum computing aims at?
