Published in 2018 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-018-3763-x

Abstract: Goos-Hänchen (GH) shifts in the reflected and transmitted light have been discussed in a cavity with four-level quantum system. It is realized that the refraction index of intracavity medium can be negative by manipulating the… read more here.

Published in 2018 at "Quantum Information Processing"

DOI: 10.1007/s11128-018-1988-5

Abstract: In this work, we point out that the multiparty secret sharing protocol of Tavakoli et al. (Phys Rev A 92:030302, 2015) based on a single d-level quantum system (where d is a prime number) is… read more here.

Published in 2019 at "Scientific Reports"

DOI: 10.1038/s41598-019-52595-7

Abstract: A fast and robust approach to controlling the quantum state of a multi-level quantum system is investigated using a twofrequency time-varying potential. A comparison with other related approaches in the context of a two-level system… read more here.

Published in 2020 at "Journal of Applied Security Research"

DOI: 10.1080/19361610.2020.1840894

Abstract: Recently, a threshold d − level quantum secret sharing scheme was presented by Song et al. However, Kao et al. showed that in contrary to Song claim, the reconstructor cannot recover the secret wit... read more here.

Published in 2020 at "Physical Review E"

DOI: 10.1103/physreve.102.052131

Abstract: We study an Otto heat machine whose working substance is a single two-level system interacting with a cold thermal reservoir and with a squeezed hot thermal reservoir. By adjusting the squeezing or the adiabaticity parameter… read more here.

Published in 2022 at "Optics express"

DOI: 10.1364/oe.449426

Abstract: Here, we focus on using composite pulses to realize high-robustness and high-fidelity coherent control in three-level quantum systems. We design the dynamic parameters (Rabi frequency and detuning) for three-level Hamiltonians for high-fidelity quantum state control… read more here.

Published in 2021 at "Symmetry"

DOI: 10.3390/sym13061013

Abstract: A method for constructing all admissible unitary non-equivalent Wigner quasiprobability distributions providing the Stratonovic-h-Weyl correspondence for an arbitrary N-level quantum system is proposed. The method is based on the reformulation of the Stratonovich–Weyl correspondence in… read more here.
