The Two-State Coin.

This is Quanta's coin. It has two faces, 0 and 1. When no one is looking it cannot pick one. When you look, it picks. Try it.

Without looking, the coin shimmers between 0 and 1.

What just happened.

A normal coin in your pocket is already heads or tails. You just have not looked yet. The two-state coin is different. Until you look, it is both. The moment you look, it becomes one of them, picked fresh every time you take it out without peeking.

Scientists call this state a qubit. Hold ten qubits together and you can ask a quantum computer questions that a normal computer would need a million years to answer. Dadi-Bot says: keep playing.
