Quantum computers are like kaleidoscopes: Why unusual metaphors help illustrate science and technology

Quantum computing is like Forrest Gump's box of chocolates: You never know what you're gonna get. Quantum phenomena—the behavior of matter and energy at the atomic and subatomic levels—are not definite, one thing or another. ...
