Quantum teleportation of an arbitrary four-qubit state via three-uniform state of eight qubits

Abstract

Recently, Zang et al. constructed a three-uniform state of eight qubits. In this work, we show that such an eight-qubit entangled state can be used to realize the deterministic quantum teleportation of an arbitrary four-qubit state based on the orthogonal basis measurement.

Quantum teleportation and state sharing using a genuinely entangled six-qubit state

Sayan Choudhury, Sreraman Muralidharan, Prasanta K Panigrahi

The usefulness of the genuinely entangled six qubit state that was recently introduced by Borras et al. is investigated for the quantum teleportation of an arbitrary three qubit state and for quantum state sharing (QSTS) of an arbitrary two qubit state. For QSTS, we explicitly devise two protocols and construct sixteen orthogonal measurement basis which can lock an arbitrary two qubit information between two parties.

Quantum teleportation of an arbitrary two-qubit state and its relation to multipartite entanglement

Gustavo Rigolin

We explicitly show a protocol in which an arbitrary two qubit state $\ensuremath{\mid}\ensuremath{\phi}⟩=a\ensuremath{\mid}00⟩+b\ensuremath{\mid}01⟩+c\ensuremath{\mid}10⟩+d\ensuremath{\mid}11⟩$ is faithfully and deterministically teleported from Alice to Bob. We construct the 16 orthogonal generalized Bell states that can be used to teleport the two qubits. The local operations Bob must perform on his qubits in order to recover the teleported state are also constructed. They are restricted only to single-qubit gates. This means that a controlled-NOT gate is not necessary to complete the protocol. A generalization where $N$ qubits are teleported is also shown. We define a generalized magic basis, which possesses interesting properties. These properties help us to suggest a generalized concurrence from which we construct a measure of entanglement that has a clear physical interpretation: A multipartite state has maximum entanglement if it is a genuine quantum teleportation channel.

Teleportation of an Arbitrary Two-Particle State via a Single Cluster-Class State

Xin-Wen Wang

Teleportation of an arbitrary two-qubit state with a single partially entangled state, a four-qubit linear cluster-class state, is studied. The case is more practical than previous ones using maximally entangled states as the quantum channel. In order to realize teleportation, we first construct a cluster-basis of 16 orthonormal cluster states. We show that quantum teleportation can be successfully implemented with a certain probability if the receiver can adopt appropriate unitary transformations after receiving the sender's cluster-basis measurement information. In addition, an important conclusion can be obtained that a four-qubit maximally entangled state (cluster state) can be extracted from a single copy of the cluster-class state with the same probability as the teleportation in principle.

Quantum teleportation of a two-qubit arbitrary entangled state with four-qubit cluster state

Hao Yuan, Min Kong, Guo‐Zhu Pan +1 more

Abstract Based on the four-qubit cluster state as quantum channel, we put forward a novel scheme for teleporting a two-qubit arbitrary entangled state. The necessary quantum operations for accomplishing the task are two controlled-not gate operations, one controlled-phase gate operation, four single-qubit measurements and two single-qubit transformed operations. They are easily achievable with current experimental techniques. Besides, the present scheme is deterministic because its probability of success is 100 % .

We demonstrate that a genuine six-qubit entangled state introduced by Tapiador et al. [J. Phys. A42 (2009) 415301] can be used to realize the deterministic controlled teleportation of an arbitrary three-qubit state by performing only the Bell-state measurements.

Quantum teleportation of an arbitrary three-qubit via three bell states

Dwi Januriyanto, Agus Purwanto, M. A. Jauhari +1 more

We report the three-qubit quantum teleportation scheme through channel six-qubit states which composed of three bell state. We apply arbitrary six-qubit state as measurement basis. This protocol can be done with classical communication of the appropriate measurement between the sender and receiver.
