Welcome back
Blochsphere 2.0
Learn quantum gates by steering a qubit across the Bloch sphere. Solve focused challenges, build custom levels, and make abstract quantum states feel visual and playable.
Qubit basics
A qubit is quantum information you can rotate.
A normal bit is either 0 or 1. A qubit can be in a superposition of both until it is measured, and its single-qubit state can be shown as a point on the Bloch sphere. Gates change that point by rotating or flipping it, which is why Blochsphere turns gate rules into something you can see.
- Superposition
- A qubit can combine the |0⟩ and |1⟩ states, with measurement probabilities set by its position.
- Measurement
- Measuring gives one classical result, but repeated runs reveal the qubit's probability pattern.
- Gates
- Quantum gates move the state around the sphere, so each move changes what outcomes are likely.
