Seiji Armstrong,Meng Wang,R. Y. Teh,Qihuang Gong,Qiongyi He,Qiongyi He,Jiri Janousek,Hans-Albert Bachor,Margaret D. Reid,Ping Koy Lam,Ping Koy Lam +10 more
TL;DR: In this paper, the Australian Research Council Centre of Excellence for Quantum Computation and Communication Technology (CE110001029) and DECRA and Discovery Project Grants schemes have been used.
Journal ArticleDOI
Secure continuous variable teleportation and Einstein-Podolsky-Rosen steering
TL;DR: It is shown that, for arbitrary Gaussian protocols and a significant class of Gaussian resources, two-way steering is required to achieve a teleportation fidelity beyond the no-cloning threshold, providing an operational connection between Gaussian steerability and secure teleportation.
Journal ArticleDOI
Genuine multipartite Einstein-Podolsky-Rosen steering.
Qiongyi He,Margaret D. Reid +1 more
TL;DR: The concept of genuine N-partite Einstein-Podolsky-Rosen (EPR) steering is developed and inequalities are derived to demonstrate multipartite EPR steering for Greenberger-Horne-Zeilinger and Gaussian continuous variable states in loophole-free scenarios.
Journal ArticleDOI
Steady Bell State Generation via Magnon-Photon Coupling.
Huaiyang Yuan,Peng Yan,Shasha Zheng,Shasha Zheng,Qiongyi He,Qiongyi He,Ke Xia,Man-Hong Yung,Man-Hong Yung +8 more
TL;DR: It is shown that parity-time (PT) symmetry can be spontaneously broken in the recently reported energy level attraction of magnons and cavity photons and may open an exciting window to utilize magnon-photon entanglement as a resource for quantum information science.
Journal ArticleDOI
Unconditional security of entanglement-based continuous-variable quantum secret sharing
TL;DR: This work establishes an unconditional security proof for entanglement-based continuous-variable quantum secret sharing schemes, in the limit of asymptotic keys and for an arbitrary number of players, and demonstrates theoretically the feasibility of the scheme, which can be implemented by Gaussian states and homodyne measurements, with no need for ideal single-photon sources or quantum memories.
