Erratum to “Scheme for remotely preparing a four-particle entangled cluster-type state” [Opt. Commun. 283 (2010) 2640–2643]

We consider the remote preparation of a six-particle cluster-type state using two four-particle GHZ states as the quantum channel in this paper. For the entangled six-particle cluster-type state with real coefficients, a deterministic remote state preparation scheme is proposed. It is shown that, conditioned on the outcome of Alice's measurement, Bob can successfully prepare the target state by performing an appropriate unitary operation. With regard to the more general six-particle cluster-type state, we give another scheme which can successfully prepare the entangled state with probability 25%. And the probability of success can reach up to 50% or even 1 in some special cases. Furthermore, the classical communication costs in different cases are discussed.

Remote Preparation of a Six-Particle Entangled Cluster-Type State

Jia

Wen

et al. 2012

“…In terms of entanglements in quantum channels, these RSP schemes can be classified into two types. One uses maximally entangled states [23,24,28,34,43,44,[50][51][52][53][54] while another utilizes non-maximally entangled states [25-27, 29, 30, 36, 45, 47, 49]. In the latter case, usually one or more auxiliary qubits need to be incorporated and entangled with the original qubits.…”

Controlled Remote Preparation of a Two-Qubit State via Positive Operator-Valued Measure and Two Three-Qubit Entanglements

Song

Wang

2011

Utilizing a proper positive operator-valued measure (POVM) instead of usual projective measurement, we present a new scheme for remote preparation of a general two-qubit state in either distant ministrant's place. In the scheme, we exploit a GHZ-type state and a W-type state as the shared quantum channel, and the remote two-qubit preparation can be realized in a probabilistic manner via two ministrants' collaboration. Furthermore, we also explore the scheme's applications to some special ensembles of states in detail. The success probabilities in different cases are calculated, respectively, which show that the remote preparation can be achieved with higher probability provided that the prepared state belongs to the special ensembles.

“…On the other hand, some RSP schemes have already been demonstrated experimentally [38][39][40][41][42][43], e.g., Peng et al presented a RSP scheme with the technique of NMR [38], Xiang et al [39] and Peters et al [40] demonstrated other two RSP schemes by spontaneous parametric down-conversion. Very recently, Ma et al [44] proposed two novel and promising RSP schemes for preparing a class of cluster-like entangled states. The schemes use four bipartite maximally entangled states and four partially entangled states as quantum channels, respectively.…”

Optimizing Scheme for Remote Preparation of Four-particle Cluster-like Entangled States

Wang

Liu

2011

Recently, Ma et al. (Opt. Commun. 283:2640, 2010 have proposed a novel scheme for preparing a class of cluster-like entangled states based on a four-particle projective measurement. In this paper, we put forward a new and optimal scheme to realize the remote preparation for this class of cluster-like states with the aid of two bipartite partially entangled channels. Different from the previous scheme, we employ a two-particle projective measurement instead of the four-particle projective measurement during the preparation. Besides, the resource consumptions are computed in our scheme, which include classical communication cost and quantum resource consumptions. Moreover, we have some discussions on the features of our scheme and make some comparisons on resource consumptions and operation complexity between the previous scheme and ours. The results show that our scheme is more economic and feasible compared with the previous.
