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.read more

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.

Efficient production of large-size optical Schrödinger cat states.
TL;DR: A novel theory of effective realization of large-size optical Schrödinger cat states, which play an important role for quantum communication and quantum computation in the optical domain using laser sources is presented.

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.
