Quantum computers are fundamentally different from classical computers due to the phenomenon of superposition, explains Monica Hansen, Head of Technical Operations at Google Quantum AI. Classical computers use bits (a computer’s smallest unit of data) that can either be 0 or 1. Quantum computers, on the other hand, use qubits, or quantum bits, that can be 0 and 1 at the same time. This ability to be in multiple states at once is a fundamental quantum mechanics principle called “superposition.” So when making a Doodle to celebrate World Quantum Day, Googler Chuck Carlson and his team of Doodle designers wanted to use a fun visual metaphor. “We loved this idea of applying the behaviors of quantum to a Doodle,” Chuck says.
