What does the Pauli-Y gate involve?

Question: What type of transformation is associated with the Pauli-Y gate? A) It only measures the qubit B) It swaps two qubits C) It flips the qubit state while also introducing a phase factor D) It deletes the target qubit Correct: C Explanation: The Pauli-Y gate combines a bit-flip-like effect with a phase factor involving the imaginary unit i. It is one of the three Pauli gates used in quantum computing. Topic: quantum computing / Pauli gates
