TL;DR: Lu et al. as mentioned in this paper constructed sixteen orthogonal measurement basis on the six photon cluster state, which will lock an arbitrary two qubit state among two parties, and showed that one can send five classical bits by sending only three qubits using this state as a shared entangled resource.

TL;DR: The present state can be used for the teleportation of an arbitrary two qubit state deterministically and the capability of the state for dense coding is investigated and it is shown that one can send five classical bits by sending only three qubits using this state as a shared entangled resource.

TL;DR: In this article, the authors studied passive environment-assisted communication via a quantum channel, where the environment is controlled by a benevolent helper, who can set its initial state such as to assist sender and receiver of the communication link.

TL;DR: This work defines and study the classical capacity of a unitary interaction with helper, in two variants: one where the helper can only prepare separable states across many channel uses, and one without this restriction.

TL;DR: In this article, the authors consider a benevolent third party, i.e., a helper, controlling the environment state, and how the helper's presence changes the communication game, and study the classical capacity of a unitary interaction with helper, indeed two variants, one where the helper can only prepare separable states across many channel uses, and one without this restriction.
