We have presented a theoretical extended version of dense coding protocol using entangled position state of two particles shared between two parties. A representation of Bell states and the required unitary operators are shown utilizing symmetric normalized Hadamard matrices. In addition, some explicit and conceivable forms for the unitary operators are presented by using some introduced basic operators. It is shown that, the proposed version is logarithmically efficient than some other multi-qubit dense coding protocols.

“…Recently, Yeo and Chua have present a genuine four-qubit entangled state |χ , and shown that it can be used to implement perfect teleportation of an arbitrary two-qubit state [10]. In fact, if we only want to teleport an unknown two-qubit entangled state, the tripartite Greenberger-Horne-Zeilinger (GHZ) state is just an ideal quantum channel [11,12]. Thus, the required quantum resource is decreased compared with the schemes in [8][9][10].…”

“…Quantum teleportation has been demonstrated by some groups [3,4,5,6] since Bennett et al [2] proposed the theoretical protocol for teleporting an unknown single qubit in 1993. Subsequently, the protocols for teleporting an entangled state are proposed with some pure entangled states or maximal multiparticle entangled states [7,8,9,10,11,12,13]. For example, Lu and Guo [11] introduced some ways for teleporting an entangled state α|00 + β|11 with entanglement swapping [14,15,16] by using EPR pairs or pure entangled states as the quantum channels in 2000.…”

Symmetric multiparty-controlled teleportation of an arbitrary two-particle entanglement

et al. 2005

We present a way for symmetric multiparty-controlled teleportation of an arbitrary two-particle entangled state based on Bell-basis measurements by using two Greenberger-Horne-Zeilinger states, i.e., a sender transmits an arbitrary two-particle entangled state to a distant receiver, an arbitrary one of the n + 1 agents via the control of the others in a network. It will be shown that the outcomes in the cases that n is odd or it is even are different in principle as the receiver has to perform a controlled-not operation on his particles for reconstructing the original arbitrary entangled state in addition to some local unitary operations in the former. Also we discuss the applications of this controlled teleporation for quantum secret sharing of classical and quantum information. As all the instances can be used to carry useful information, its efficiency for qubits approaches the maximal value.Horne-Zeilinger (GHZ) state |ψ L = 1 √ 2 (|1010 + |0101 ). Recently, Rigolin [17] showed a way to teleport an arbitrary two-qubit entangled state with a four-particle entangled state |ψ R = 1 2 (|0000 + |0101 + |1010 + |1111 ) and four-particle joint measurements.Recently, controlled teleporation for a single-qubit |χ = a| ↑ + b| ↓ [33,34] [35] have been studied. In those teleportation protocols, the qubits can be regenerated by one of the receivers with the help of the others. Those principles can be used to split a quantum secret in QSS [19]. In this paper, we will present a symmetric protocol for multiparty-controlled teleportation of an arbitrary two-particle entangled state with two GHZ states and
