Joint Research Of Remote Preparation Of Arbitrary Three Qubits State

Quantum entanglement is the basic concept of quantum information, is one of the mostwonderful, the most incredible phenomenon of quantum mechanics, and differs from classicalphysics. Quantum entanglement is considered as an irreplaceable resource, which can be used toperform some tasks that classic means cannot complete. Quantum information arises from thecombination of quantum theory and information science. Due to so many new features of quantummechanics, such as superposition, coherence, non-locality and non-clone, etc., the quantuminformation shows the unique features unmatched by Classic informatics in the information field.Quantum communication and quantum computing are two main branches of quantum informationscience. Secure and faithful transmission of quantum information encoded in a quantum statebetween remote locations is a basic task in quantum network communication. In1993, Bennett etal. proposed the scheme of quantum teleportation, this transmission scheme transmit an unknownqubit from one site to another via the shared quantum entanglement, without sending the stateitself physically. This transmission scheme demonstrates the interchangeability of different typesof resources and has been made considerable progresses. Subsequently, remote state preparation,joint remote state preparation has been proposed and has been widely studied.Recently, luo et al. presents some protocols that several senders jointly prepare an arbitrarythree-qubit state to a remote receiver use three GHZ states as quantum channels. Chen et al.targeted the limitations of luo’s measurement bases devised a scheme that allows two parties tojointly prepare for a third remote party the most general three-qubit state characterized by arbitrarycomplex coefficients. However, chen only discussed one form of the generalized Bell states, butdid not consider the other three groups of EPR pairs. Thus there is no comparison of differentforms of EPR pairs.In this paper, we propose a scheme to realize a joint remote preparation of an arbitrarythree-qubit state using the four different types of EPR pairs of the generalized Bell states asquantum channel. By the specific examples, we show the joint remote state preparation steps indetail. The results show that different forms of EPR pairs as quantum channel, receiver need tocarry out different forms of recovery operations under the measurement results, but theircontribution to the probability of the joint remote state preparation is the same. If the shared pairsare all maximally entangled, we can get the maximum success probability.
