Q37.Phase Oracle Inversion for |00⟩

Amplitude AmplificationQubits: 2Q
Implement the phase oracle U0=I−2∣00⟩⟨00∣U_0 = I - 2|00\rangle\langle 00| that marks ∣00⟩|00\rangle with a −1-1 relative phase.
Target Objective:
Put qubits in superposition, wrap CZ with Pauli-X on both qubits, and verify the resulting statevector.
Judge Acceptance Criteria:

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