How the Different Kinds of Qubits Work
Every quantum platform has its own way of storing information, steering qubits, linking pairs, and reading the answer. Take a relaxed scroll through five popular approaches and tap on the cards that spark your curiosity.

Qubi (Hands-on Metaphor)
Playful, tangible intuition for a single qubit.
Ready
Measurement
Shake it in a particular direction and the dot flashes that answer.
Single-Qubit Rotations
Twist the sphere to steer the dot anywhere you like.
Entanglement
Bump two spheres together so their dots stay in sync.
Trapped Ion Qubits
Each electron is actually a tiny little magnet. It has a North Pole and a South Pole. The qubit is: the direction that the North Pole is pointing.

Photon Polarization Qubits
Photons have a property called “polarization”. Polarization is the direction that the photon wiggles as it moves forward. Photons can wiggle up-and-down, side-to-side, or even in a circle.
