Question: In a CNOT gate, what is the target qubit? A) The qubit that is always measured first B) The qubit that may be flipped depending on the control qubit C) The qubit that stores the number of shots D) The qubit that is deleted after the operation Correct: B Explanation: In a CNOT gate, the target qubit is flipped only when the control qubit is in state |1⟩. If the control is |0⟩, the target remains unchanged. Topic: quantum computing / CNOT / two-qubit gates
