Deterministic joint remote state preparation of arbitrary two- and three-qubit states

Abstract

We propose a novel deterministic protocol that two senders are capable of remotely preparing arbitrary two-and three-qubit states for a remote receiver using EPR pairs and GHZ state as the quantum channel. Compared with the existing deterministic protocols [An et al. 2011 Phys. Lett. A 375 3570 and Chen et al. 2012 J. Phys. A: Math. Theor. 45 055303], the quantum resources and classical information in our scheme are decreased, and the whole operation process is simplified.

Efficient schemes of joint remote preparation with a passive receiver via EPR pairs

“…The reason is that there does not exist the necessary joint system operations for general complex coefficients. Therefore, similar to previous deterministic JRSP protocols, [28][29][30][31][32][33][34][35][36] the classical information {x j = r j e iθ j } of prepared state is split into phase information {r j } and amplitude information {θ j } respectively in this paper. In detail, the state in Eq.…”

“…Since the first appearance of JRSP, [20] various JRSP schemes using different types of quantum entanglement have been presented. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] Most existing JRSP protocols are probabilistic. Also, a new direction named deterministic JRSP has been put forward to get the unit success probability.…”

“…Also, a new direction named deterministic JRSP has been put forward to get the unit success probability. [28][29][30][31][32][33][34][35][36] Recently, Xia et al proposed a deterministic JRSP scheme of an arbitrary three-qubit state with a passive receiver. [33] They use the simplest kind of entanglement resource EPR pairs as the quantum channel since the EPR pair can be more easily produced and distributed than the GHZ ones.…”

Deterministic joint remote preparation of an arbitrary two-qubit state in noisy environments

“…In JRSP, the initial state can be remotely reconstructed only under the cooperation of all the senders. Subsequently, JRSP has been further generalized [24][25][26][27][28][29], and some protocols for deterministic joint remote preparation of arbitrary single-qubit, two-qubit, three-qubit, and multi-qubit states has been suggested [30][31][32][33][34][35][36][37] via different types of entangled channels.…”

Deterministic assisted clone of an unknown four-particle entangled cluster-type state

“…The other is that by making use of the leftover entangled resource after the teleportation, [19][20][21][22] the sender establishes a quantum channel between the preparer and her, and then the preparer carries out the remote state preparation (RSP). [23][24][25][26][27][28] However, these assisted-clone protocols succeed with a finite probability that is less than one, which means that they cannot always generate the perfect copy of the unknown state deterministically.…”
