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, which utilizes quantum encryption technology to overcome the information leakage problem. In the proposed QD protocol, during the transmission process, the single photons in both polarization and spatial-mode degrees of freedom used for encoding two communicants’ private classical bits are protected by both quantum…

Quantum Secure Dialogue with Quantum Encryption
TLDR
A novel approach for sharing the initial quantum state privately between communicators, i.e., quantum encryption sharing, is proposed by utilizing the idea of quantum encryption, which uses EPR pairs as the private quantum key to encrypt and decrypt the traveling photons.
Three-party Quantum Secure Direct Communication with Single Photons in both Polarization and Spatial-mode Degrees of Freedom
We present an efficient three-party quantum secure direct communication (QSDC) protocol with single photos in both polarization and spatial-mode degrees of freedom. The three legal parties’ messages…
Efficient quantum private comparison employing single photons and collective detection
TLDR
Two efficient quantum private comparison protocols are proposed, employing single photons and collective detection to compare the equivalence of information with the help of a semi-honest third party.
Quantum secure dialogue by using single photons
Quasi-secure quantum dialogue using single photons
TLDR

BIDIRECTIONAL QUANTUM SECURE DIRECT COMMUNICATION IN DRIVEN CAVITY QED
A theoretical scheme of bidirectional quantum secure direct communication is proposed in the context of driven cavity QED. We first present an entanglement swapping scheme in cavities where two atoms…
Secure quantum dialogue based on single-photon
TLDR
It is shown that the intercept-and-resend attack and coupling auxiliary modes attack can be resisted more efficiently, because the photons are sent only once in the quantum dialogue scheme.
