TLDR
In this paper, the authors considered a type of entangled coherent states and proposed a simple deterministic scheme to generate these states that can fly freely in space, and then exploited such free-flying states to teleport certain kinds of superpositions of multimode coherent states.
Abstract
We consider a type of $(M+N)$-mode entangled coherent states and propose a simple deterministic scheme to generate these states that can fly freely in space. We then exploit such free-flying states to teleport certain kinds of superpositions of multimode coherent states. We also address the issue of manipulating size and type of entangled coherent states by means of linear optics elements only.

Joint remote preparation of four-qubit cluster-type states revisited

TL;DR: In this article, the authors revisit the protocols proposed recently (Zhan et al 2011 J. Phys. B: At. Mol. Opt. 44 095501) for joint remote preparation of four-qubit cluster-type states.

Coherent-state optical qudit cluster state generation and teleportation via homodyne detection

TL;DR: In this paper, a coherent state of large amplitude, | α | ⪢ d / 2 π, is interpreted as a qudit, a d-level quantum system that is an even (meaning same size of amplitudes) superposition of d pseudo-number basis states.

Deterministic Joint Remote Preparation of an Arbitrary Qubit via Einstein-Podolsky-Rosen Pairs

TL;DR: This work proposes a new deterministic protocol for two parties to remotely prepare an arbitrary single-qubit state for a third party using two Einstein-Podolsky-Rosen pairs as the nonlocal resource and figures out the advantages as well as the disadvantages of this new protocol in comparison with others.

Efficient production of large-scale optical Schrodinger cat states

TL;DR: In this article, a theory of effective realization of large-scale optical Schrodinger cat states is presented, which is based on the theory of large scale optical Schroffinger states.
