“No, no, no don’t interrupt me. 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.

“Normal computers work, either there’s 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. A regular computer bit is either a one or a zero: on or off. A quantum state can be much more complex than that because as we know, things can be both particle and wave at the same times, 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.”
