Bloch Sphere Explorer

Visualize a single qubit as a point on the sphere. Adjust θ and φ, or apply gates.

θ (theta) — 0.00 radφ (phi) — 0.00 rad

State

|ψ⟩ = cos(θ/2)|0⟩ + e^iφ sin(θ/2)|1⟩

P(0) = 1.000

P(1) = 0.000

For beginners

The Bloch sphere is a map of every single-qubit state. The north pole is |0⟩ and the south pole is |1⟩. Points on the equator are equal superpositions differing only in phase.
