. >> mrning, 4:30 to 7:00 a.m. >>> welcome back to "press here." we're going of a variety of ways to explain very simply what quantum computing is. one explanation involved a dead cat. but it turns out one of the best people to explain quantum computing is the prime minister of canada. a reporter famously said to the prime minister during a question and answer session, i don't expect you to understand quantum computing, to which the prime minister said this. >> very simply, normal computers work by -- no, no, no, don't interrupt me. when you walk out of here, you will know more -- no, some of you will far less about quantum computing, but most of you, normal computers work, either there's power going through a wire or not. it's a 1 or a 0. 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 whether a 1 or a 0, 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 time, and the un
