Abstract: We present a novel scheme for deterministically realizing remote preparation of three-dimensional quantum states in a controlled manner. In this scheme, to link the three legitimate parties, generalized Einstein-Podolsky-Rosen (EPR) states, generalized Greenberger-Horne-Zeilinger (GHZ) states… read more here.

Abstract: We construct the convex set $$\mathcal{M}$$M of two-qutrit states, and the subset $$\mathcal{P}\subset \mathcal{M}$$P⊂M. We characterize the extremal points of rank one and rank two of $$\mathcal{M}$$M. We further show that the extremal points of… read more here.

Abstract: We introduce a family of anisotropic two-qutrit states (AITTSs). These AITTSs are expressed as ρaiso=p|ψ(θ,ϕ)⟩⟨ψ(θ,ϕ)|+(1−p)I99 with |ψ(θ,ϕ)⟩=sin⁡θcos⁡ϕ|00⟩+sin⁡θsin⁡ϕ|11⟩ +cos⁡θ|22⟩ and I9=∑j,k=02|jk⟩⟨jk|. For a given p∈[0,1], these states are adjustable in different ( θ,ϕ) directions. In the… read more here.

Abstract: Gate-based quantum computation has been extensively investigated using quantum circuits based on qubits. In many cases, such qubits are actually made out of multilevel systems but with only two states being used for computational purpose.… read more here.

Abstract: While it has recently been demonstrated how to certify the maximal amount of randomness from any pure two-qubit entangled state in a device-independent way, the problem of optimal randomness certification from entangled states of higher… read more here.
