Quantum Superposition

Being in many states at once.

Quantum superposition is a fundamental principle of quantum mechanics that states a quantum system, such as an electron or a photon, can exist in multiple states simultaneously until a measurement is performed. In classical physics, an object is always in a single, definite state.

🎰 A way for quantum bits to be 'maybe yes' and 'maybe no' at the same time, allowing them to skip ahead to the answer.

## The Power of Phase
- Superposition: $|\psi angle = \sum c_i |i angle$
- Interference: Adjusting $c_i$ to amplify or suppress outcomes.
- Collapse: The transition from $|\psi angle$ to a single $|i angle$ upon interaction.
