Insecurity of Jiang et al.’s quantum cryptography protocol

Abstract

Recently, Jiang et al. proposed a quantum cryptography protocol [Mod. Phys. Lett. B 32 (2018) 1850125] which can implement the equal exchange of secret information between the two parties with the help of semi-trusted third party. Here, it will be shown that the protocol is insecure and has the drawback of information leakage.

Possible Candidates for Chirality in the Odd-Odd As Isotopes

“…Such bands were claimed to be observed in 131 Ba recently. [32] The present calculations demonstrate the coexistence of chiral and pseudospin symmetries in the As isotopes. It should be noted that the pseudospin symmetry with the triaxial deformation is still an open problem.…”

Knowledge of doubly strange hypernuclei and experimental prospect

“…Those events were interpreted to decay into (1) 4 H + 9 Be and (2) 4 H + 9 Be . The papers for each event introduced B to be 0.54 MeV (1) [12] and 0.62 MeV (2) [13] with 0.2 MeV errors. Although we and some theorists discussed the presence of a Coulombassisted nuclear 2p state in hypernucleus, some claimed that they were consistent with atomic 3D level (0.13 MeV) [14].…”

“…With the development of the overall-scanning method, we shall detect one thousand samples of doubly strange hypernuclei in the future. Then, by using the E07 emulsion, it will be sure that knowledge on doubly strange hypernuclei becomes much richer on, for example,interaction for not only two s in the ground state but one in an excited state, and more precise measurement of level scheme for 13 B and 17 N as well as 15 C. In addition to them, precise measurement of B of single-hypernuclei, which is expected for 1 million events, shall be performed and hypernuclei can be studied with a p-bar beam which was exposed in the emulsion for position calibration for emulsion sheet by sheet.…”
