At the heart of how quantum computers work are tiny things called qubits. A qubit is like a regular computer bit, which is either a 0 or a 1, but it’s way more special. Thanks to something called superposition, a qubit can be a 0, a 1, or both at the same time. Imagine spinning a coin, it’s not just heads or tails while it’s in the air; it’s kind of both until it lands.
