Published in 2017 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-017-3506-4

Abstract: Classical public key cryptosystems (PKC), such as RSA, EIGamal, ECC, are no longer secure in quantum algorithms, and quantum cryptography has become a novel research topic. In this paper we present a quantum asymmetrical cryptosystem… read more here.

Published in 2019 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-019-04252-y

Abstract: Semi-quantum protocol uses fewer resources and more flexible, which can still guarantee the unconditional safety. Based on Bell states, this paper first presents a semi-quantum key agreement protocol which allows two classical parties (Alice and… read more here.

Published in 2019 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-019-04281-7

Abstract: Semi-Bell states are exploited for storing and sending information in non-inertial frames. In this paper, we consider four types of semi-bell states, $|{\varPhi }_{\alpha }^{\pm }\rangle =\alpha |0\rangle |0\rangle \pm \sqrt {1-\alpha ^{2}}|1\rangle |1\rangle $… read more here.

Published in 2020 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-020-04578-y

Abstract: Shared quantum entanglements are rare resources and widely used in various quantum information processing. They are thought sometimes to be more important than local operation and classical communication. In this paper a shared mixing entangled… read more here.

Published in 2021 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-021-04927-5

Abstract: Ma et al. [Int. J. Theor. Phys. (2021): 1328–1338] proposed a multi-party quantum key distribution (MQKD) protocol using Bell states, in which multiple participants can distribute a group key efficiently. However, this study indicates that… read more here.

Published in 2020 at "Quantum Information Processing"

DOI: 10.1007/s11128-020-02719-0

Abstract: The time-variant quantum communication channel affected by uncontrollable environmental factors induces an unrepeatable evolution of Bell states, which calls for a universal method of evolution reconstruction. The novel Fourier-based method proposed recently is extended and… read more here.

Published in 2018 at "Modern Physics Letters B"

DOI: 10.1142/s0217984918502949

Abstract: A recent paper proposed a semi-quantum secret sharing (SQSS) scheme based on Bell states [A. Yin et al., Mod. Phys. Lett. B. https://doi.org/10.1142/S0217984917501500]. This protocol was presumed t... read more here.

Published in 2020 at "International Journal of Quantum Information"

DOI: 10.1142/s0219749920500185

Abstract: We give the explicit expressions of quantum Fisher information and skew information for a two-qubit Bell states. We investigate their dynamics under the decoherence effects: phase-damping channel, ... read more here.

Published in 2019 at "Entropy"

DOI: 10.3390/e21040402

Abstract: A scheme is proposed to generate maximally entangled states of two Λ-type atoms trapped in separate overdamped optical cavities using quantum-jump-based feedback. This proposal can stabilize not only the singlet state, but also the other… read more here.
