Q15.Bell State |Φ-⟩ Generation

Quantum EntanglementQubits: 2Q
Construct the orthogonal Bell state ∣Φ−⟩=12(∣00⟩−∣11⟩)|\Phi^-\rangle = \frac{1}{\sqrt{2}}(|00\rangle - |11\rangle) starting from ∣00⟩|00\rangle.
Target Objective:
Add a Phase (Z) gate to the standard Bell state generator to introduce the −1-1 relative phase between ∣00⟩|00\rangle and ∣11⟩|11\rangle.
Judge Acceptance Criteria:

Statevector fidelity must reach ≥ 99.9% with the target unitary solution.
