“…Theoretically, since the work of Bennett et al [1] on teleporting a qubit of unknown information with the aid of Einstein-PodolskyRosen (EPR) correlation, quantum teleportation has been extended from discrete-variable systems to continuous-variable systems [2][3][4][5] and also from a single qubit to multiqubits [6][7][8][9]. On the other hand, recent experiments have demonstrated quantum teleportation with photon-polarized states [10], optical coherent states [11], and nuclear magnetic resonance [12].…”

We present a way to teleport multiqubit quantum information from a sender to a distant receiver via the control of many agents in a network. We show that the original state of each qubit can be restored by the receiver as long as all the agents collaborate. However, even if one agent does not cooperate, the receiver cannot fully recover the original state of each qubit. The method operates essentially through entangling quantum information during teleportation, in such a way that the required auxiliary qubit resources, local operation, and classical communication are considerably reduced for the present purpose.

“…In the above equations, the notes "±" from right to left correspond to signs of the Bell state of particles (1,4), (2,6) and (3,8) that are shown in (3). Assume Alice performs Bell-basis measurement on particles (1, 4), (2,6) and (3,8), respectively, and if the measurement outcome of Alice is |Φ − 14 |Ψ + 26 |Ψ + 38 (the probability of this result is only 1/64), then the resulting nine-particle state can be written as…”

In this paper, we propose a protocol which can realize quantum cloning of an unknown tripartite entangled state and its orthogonal complement state with assistance from a state preparer. The first stage of the protocol requires usual teleportation via three entangled particle pairs as quantum channel. In the second stage of the protocol, the perfect copies and complement copies of an unknown state can be produced with the assistance (through a tripartite projective measurement) of the state preparer. We also present a scheme for the teleportation by using non-maximally entangled quantum channel. It is shown that the clones and complement clones of the unknown state can be obtained with certain probability in the latter scheme.

“…As a practical application, teleportation has been implemented experimentally in several quantum systems [2,3], and could be very useful for achieving quantum repeaters [4], quantum networks [5], and also quantum computing [6]. Recently, much attention has been paid on teleportation of multipartite states [7,8,9]. It has been shown that an arbitrary two-qubit state can be teleported using the multipartite entangled state as quantum channel [9].…”

Abstract. We propose a practical scheme for deterministically teleporting an arbitrary multipartite state, either product or entangled, using Faraday rotation of the photonic polarization. Our scheme, based on the input-output process of single-photon pulses regarding cavities, works in low-Q cavities and only involves virtual excitation of the atoms, which is insensitive to both cavity decay and atomic spontaneous emission. Besides, the Bell-state measurement is accomplished by the Faraday rotation plus product-state measurements, which could much relax the experimental difficulty to realize the Bell-state measurement by the CNOT operation.
