Abstract

We present a controlled secure quantum dialogue protocol using a non-maximally (pure) entangled Greenberger-Horne-Zeibinger (GHZ) states at first, and then discuss the requirements for a real quantum dialogue. We show that the authorized two users can exchange their secret messages after purifying the non-maximally entangled GHZ states quantum channel unconditionally securely and simultaneously under the control of a third party.
