Two Semi-Quantum Direct Communication Protocols with Mutual Authentication Based on Bell States
TL;DR: Two semi-quantum direct communication protocols based on Bell states are proposed that can resistant to several well-known attacks and their qubit efficency is higher than some current protocols.

Quantum Fisher Information of a 3-Qubit State
TL;DR: In this article, the properties of quantum Fisher information in a general superposition of a 3-qubit GHZ state and two W states were investigated, and the mean spin direction, the length of mean spin and quantum fisher information were determined by the coefficients of superposition and the relative phase between the GHZ states and the W states.

Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels
Charles H. Bennett,Gilles Brassard,Claude Crépeau,Richard Jozsa,Asher Peres,William K. Wootters +5 more
TL;DR: An unknown quantum state \ensuremath{\Vert}\ensure Math{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) correlations.

Experimental quantum teleportation
TL;DR: In this article, the authors demonstrated the feasibility of quantum teleportation over arbitrary distances of the state of a quantum system by using a measurement such that the second photon of the entangled pair acquires the polarization of the initial photon.

Quantum state transfer and entanglement distribution among distant nodes in a quantum network
TL;DR: In this paper, a scheme to utilize photons for ideal quantum transmission between atoms located at spatially separated nodes of a quantum network was proposed, which employs special laser pulses that excite an atom inside an optical cavity at the sending node so that its state is mapped into a time-symmetric photon wave packet that will enter a cavity at receiving node and be absorbed by an atom there with unit probability.

Experimental Realization of Teleporting an Unknown Pure Quantum State via Dual Classical and Einstein-Podolsky-Rosen Channels

TL;DR: In this article, a quantum optical experimental implementation of teleportation of unknown pure quantum states was reported, which realizes all of the nonlocal aspects of the original scheme proposed by Bennett et al. and is equivalent to it up to a local operation.
