Abstract ：Based on the deterministic secure quantum communication, we present a novel quantum dialogue protocol without information leakage over the collective noise channel. The logical qubits and four-qubit decoherence-free states are introduced for resisting against collective-dephasing noise, collective-rotation noise and all kinds of unitary collective noise, respectively. Compared with the existing similar protocols, the analyses on security and information-theoretical efficiency show that the proposed protocol is more secure and efficient.
