In this paper, a novel quantum dialogue (QD) protocol is proposed based on single photons in both polarization and spatial-mode degrees of freedom. In the proposed QD protocol, the initial states of single photons in both polarization and spatial-mode degrees of freedom used for encoding are privately shared between two communicants through the direct transmissions of their auxiliary counterparts from one communicant to another. As a result, the information leakage problem is avoided. Moreover, the detailed security analysis also shows that the proposed QD protocol can resist Eve's several famous active attacks, such as the Trojan horse attack, the intercept-resend attack, the measure-resend attack and the entangle-measure attack. The proposed QD protocol only needs single photons in both polarization and spatial-mode degrees of freedom as quantum resource and adopts single-photon measurements. As a result, it is feasible in practice as the preparation and the measurement of a single photon in both polarization and spatial-mode degrees of freedom can be accomplished with current experimental techniques.

In this paper, a novel information-leakage-resistant quantum dialogue (QD) protocol with single photons in both polarization and spatial-mode degrees of freedom is proposed. This protocol utilizes quantum encryption technology to overcome the information leakage problem; the protocol utilizes quantum encryption and decoy photon technologies to dually protect the single photons with two degrees of freedom used for encoding two communicants' private classical bits, and makes the initial states of the single photons with two degrees of freedom for encoding shared between two communicants through quantum key encryption and decryption. The information-theoretical efficiency of this protocol is 40%.

“…Subsequently, researchers quickly turned to study how to solve the information leakage problem existing in QD. Until now, many excellent methods have been suggested, such as utilizing the direct transmission of auxiliary quantum states [30][31][32][33][34][35][36][37], the correlation extractability of Bell states [38], controlled-not operations and auxiliary single photons [39], the measurement correlation from entanglement swapping of quantum entangled states [40][41], the encoding for collections composed by the entanglement swapping results of quantum entangled states [34][35][36], quantum encryption sharing [42][43], auxiliary quantum operations [44] and the measurement correlation of quantum entangled states [45].…”

“…It is easy to discover that all of the above QD protocols [19][20][21][22][23][24][25][26][27][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] require both parties to possess quantum capabilities which may be unpractical in some circumstances, as not both parties have the abilities to afford expensive quantum resources and operations. Whether the dialogue can be successfully accomplished if there is only one party who has quantum capabilities?…”

In this paper, we propose two semi-quantum dialogue (SQD) protocols by using single photons as the quantum carriers, where one requires the classical party to possess the measurement capability and the other does not have this requirement. The security towards active attacks from an outside Eve in the first SQD protocol is guaranteed by the complete robustness of present semi-quantum key distribution (SQKD) protocols, the classical one-time pad encryption, the classical party's randomization operation and the decoy photon technology. The information leakage problem of the first SQD protocol is overcome by the classical party' classical basis measurements on the single photons carrying messages which makes him share their initial states with the quantum party. The security towards active attacks from Eve in the second SQD protocol is guaranteed by the classical party's randomization operation, the complete robustness of present SQKD protocol and the classical one-time pad encryption. The information leakage problem of the second SQD protocol is overcome by the quantum party' classical basis measurements on each two adjacent single photons carrying messages which makes her share their initial states with the classical party. Compared with the traditional information leakage resistant QD protocols, the advantage of the proposed SQD protocols lies in that they only require one party to have quantum capabilities. Compared with the existing SQD protocol, the advantage of the proposed SQD protocols lies in that they only employ single photons rather than two-photon entangled states as the quantum carriers. The proposed SQD protocols can be implemented with present quantum technologies.
