Bloch Sphere Explorer

Visualize single-qubit quantum states on the 3D Bloch sphere. Apply gates and watch the state vector transform in real-time.

Interactive 3D

Click and drag to rotate the sphere, use mouse wheel to zoom in and out

Quantum Gates

Apply X, Y, Z, H, S, T and other gates to see real-time state transformations

State Visualization

See the state vector and amplitudes update as you apply quantum operations

Interactive Bloch Sphere

The Bloch Sphere is a geometrical representation of a single qubit's quantum state. The north pole represents |0⟩, the south pole represents |1⟩, and all other points on the sphere represent different superposition states.

How to Use

  • Rotate: Click and drag to rotate the Bloch sphere
  • Zoom: Use mouse wheel or pinch to zoom in/out
  • Apply Gates: Click the quantum gate buttons on the right (X, Y, Z, H, S, T, etc.) to transform the state
  • Watch the State: The vector shows the current qubit state. The state amplitudes are displayed at the top
  • Reset: Click the reset button to return to |0⟩ state
