Q26.Deutsch Oracle: Constant-1 Function f(x) = 1

Quantum ParallelismQubits: 2Q
Implement Deutsch algorithm for oracle f(x)=1f(x)=1, which applies an unconditional bit-flip (Pauli-X) on the ancilla qubit.
Target Objective:
Prepare ancilla Q1 in ∣−⟩|-\rangle, put Q0 in ∣+⟩|+\rangle, apply Pauli-X on Q1 as the oracle, and apply Hadamard on Q0 to measure ∣0⟩|0\rangle with 100% probability.
Judge Acceptance Criteria:

Measurement probability for designated basis state must reach ≥ 95%.
