Q36.Phase Oracle Inversion for |11⟩Easy

Q36.Phase Oracle Inversion for |11⟩

Amplitude AmplificationQubits: 2Q
Implement the phase oracle Uf=I−2∣11⟩⟨11∣U_f = I - 2|11\rangle\langle 11| that flips the sign of the marked item ∣11⟩|11\rangle.
Target Objective:
Initialize qubits in equal superposition and apply a Controlled-Z (CZ) gate to achieve negative phase on ∣11⟩|11\rangle.
Judge Acceptance Criteria:

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