“…Chang et al proposed a QDP based on the entanglement of GHZ states to resist the collectivedephasing noise and collective-rotation noise [7,8]. Wang et al indicated two legitimate users could transmit their secret messages directly by combining the generalized Bell-basis measurement with classical communication [9].…”

A new quantum network dialogue protocol is designed by using the entanglement property of the continuous-variable single-mode squeezed states. To verify the security of the channel in the protocol, Alice should send single-mode squeezed states respectively to Bob, Charlie, and etc. Then Bob, Charlie et al could encode the secret information with a specific encoding rule, insert the Gaussian random data into the encoded message and send them to Alice. They could deduce the secret information of their counterparts according to the measurement results. In addition, each communication party could dialogue with another communicator in a quantum way. The new proposed quantum network dialogue protocol based on single-mode squeezed states is much easier to implement compared with those based on the discrete-variable quantum states.

“…In 2004, another novel kind of quantum secure communication, called Quantum dialogue (QD), was put forward by Nguyen et al [5] and it permits the two participants to exchange their respective secret messages simultaneously. Up to now, various QD protocols have been proposed based on single photons [6][7][8][9][10][11][12][13] or entanglement states [5,14]. The security, efficiency and practicability are the focus of quantum communication protocols.…”

A new quantum dialogue (QD) protocol with single photons is proposed. In the proposed protocol, two participants perform different operations according to their own secret information. A key previously shared by the two communicants through a secure QKD protocol is used to control not only the encoding operation of the dialogue initiator but also security detection. The analysis on efficiency demonstrates the proposed protocol is more efficient.

“…In recent years, several other protocols referred to as BQSDC [9,10], quantum telephone [11], quantum dialogue [12], quantum conversation [13], etc, have also been proposed using (i) dense coding [8], (ii) auxiliary particles [9], (iii) entangled states [10,14], (iv) single photon [12,15,16], (v) entanglement swapping [17], (vi) two-photon entanglement [18,19], etc. These are actually different names used for equivalent protocols, and there are subtle differences in these protocols.…”

A quantum dialogue protocol is proposed based on four-qubit entangled state, which is constructed by an EPR pair and two different single qubits through three controlled-not gates. By using Bell measurements and the corresponding unitary operation, two users can exchange their messages simultaneously and directly without sharing any secret keys beforehand. Security analysis shows that this protocol can resist the-interceptresend attack and the entanglement-measure attack. The protocol is simple and feasible with current technique.
