First BlackRoad AI quantum node: talk to ψ, see predictions, and map them to ⟨Z⟩ and probabilities.
BRQ-01 takes a 2D feature vector x = [x₀, x₁] and returns
the probability for class 1. We compute the implied ⟨Z⟩ using
⟨Z⟩ = 1 - 2p₁.
Want to see how ψ thinks under the hood? Open Math Lab (Σ) from the terminal:
1 - Vectors → Qubits → ψ2 - Matrices → Gates → RX/RY/RZ3 - Inner Products & ⟨ψ|φ⟩4 - Tensor Products & Entanglement5 - Live BRQ-01 Demo (ψ on this Pi)
Run: python3 ./blackroad-math-lab.py or press m in the menu.
