Published in 2018 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-018-3748-9

Abstract: We present a scheme for bidirectional controlled quantum teleportation (BCQT) via a five-qutrit entangled state as the quantum channel. In this scheme, two distant parties, Alice and Bob, are not only senders but also receivers,… read more here.

Published in 2019 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-019-04244-y

Abstract: We first put forward an efficient protocol in ideal environment to deterministically realize bidirectional hybrid quantum communication via a five-qubit entangled state as the quantum channel, where both the senders transfer an arbitrary single-qubit state… read more here.

Published in 2021 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-021-04895-w

Abstract: In this paper, a controlled quantum dialogue protocol is designed based on five-qubit entangled states. One five-qubit entangled state can be used to exchange one communicant’s two private bits with the other communicant’s two private… read more here.

Published in 2019 at "Quantum Information Processing"

DOI: 10.1007/s11128-019-2343-1

Abstract: AbstractRecently, a new controlled quantum dialogue (CQD) protocol which is secure against the conspiring attack from the users without the controller’s permission was put forward. However, it is found that this CQD protocol is weak… read more here.

Published in 2017 at "Scientific Reports"

DOI: 10.1038/s41598-017-02757-2

Abstract: Quantum Hall ferromagnetic transitions are typically achieved by increasing the Zeeman energy through in-situ sample rotation, while transitions in systems with pseudo-spin indices can be induced by gate control. We report here a gate-controlled quantum… read more here.

Published in 2020 at "Scientific Reports"

DOI: 10.1038/s41598-020-73275-x

Abstract: We theoretically study the average current through a ring embedded with multiple quantum dots in each arm subjected to a time-dependent external field. A current resonance band can be observed in a six-quantum-dot system. In… read more here.

Published in 2018 at "Applied Physics Letters"

DOI: 10.1063/1.5007935

Abstract: Deterministic integration of site-controlled quantum dots with photonic crystal waveguides is demonstrated, which allows positioning the dots for optimal overlap with the waveguide modes. The coupling efficiency (β-factor) of quantum dot emission to propagating waveguide… read more here.
