Module husimi 

Husimi Q-distribution visualization for quantum states.

Evaluates Q(θ, φ) = |⟨α(θ,φ)|^⊗n |ψ⟩|² on a 64×64 grid over the sphere (θ ∈ [0,π], φ ∈ [0,2π]), where |α(θ,φ)⟩ is the single-qubit SU(2) coherent state and the n-qubit coherent state is the tensor product |α⟩^⊗n.

Functions

husimi_plotly_json

Returns a Plotly-JSON string for a Husimi Q-distribution surface plot.
