Recently, a genuine five-qubit entangled state [Formula: see text] has been proposed by Man et al. In this paper, we present a simple scheme for generating such a state in ion trap and cavity QED, respectively. This study offers a new approach to faithful controlled teleportation of an arbitrary two-qubit state in these two systems.

We put forward an efficient quantum controlled teleportation scheme, in which arbitrary two-qubit state is transmitted from the sender to the remote receiver via two entangled states under the control of the supervisor. In this paper, we use the combination of one two-qubit entangled state and one three-qubit entangled state as quantum channel for achieving the transmission of unknown quantum states. We present the concrete implementation processes of this scheme. Furthermore, we calculate the successful probability and the amount of classical information of our protocol.

Quantum Secret Sharing Scheme

Semi-quantum secret sharing (SQSS) can transmit secret messages. Most existing SQSS protocols can only use one or two specific entangled states to share unspecific or specific classical message. In this paper, we propose a novel SQSS protocol using N different unspecific two-particle entangled state [Formula: see text], [Formula: see text] to share unspecific message, in which quantum Alice can transmit classical messages with classical Bob and Charlie. In addition, we have proved that the protocol can strongly resist some forms of eavesdropping.

We present a simple scheme for the preparation of entangled states of the e.m. modes of two spatially separated microwave cavities exploiting their interaction with two superconducting SQUID rings embedded within them. The scheme requires that the two SQUID qubits are initially prepared in an entangled state and the possibility of controlling both the coupling strengths and the interaction times. We also briefly discuss the importance of such a theoretical scheme in view of possible applications in the context of quantum computing and its experimental feasibility.

It is shown that some of these states can be utilized for perfect teleportation of arbitrary two-qubit systems and controlled teleportation of an arbitrary one-qubit state. Furthermore, the optimal match measuring basis are given by transformation operator for controlled teleportation.

Partially Entangled Channel

In this paper, we present a deterministic four-party quantum cyclic controlled teleportation (QCYCT) scheme, by using a multi-qubit partially entangled state as the quantum channel. In this scheme, Alice can teleport an arbitrary [Formula: see text]-qubit state to Bob, Bob can teleport an arbitrary [Formula: see text]-qubit state to Charlie and Charlie can teleport an arbitrary [Formula: see text]-qubit state to Alice under the control of the supervisor David. We utilize rotation gate, Hadamard gates and controlled-NOT (CNOT) gates to construct the multi-qubit partially entangled channel. Only Bell-state measurements, single-qubit von-Neumann measurement and proper unitary operations are required in this scheme, which can be realized in practice easily based on the present quantum experiment technologies. The direction of cyclic controlled teleportation of arbitrary multi-qubit states can also be changed by altering the quantum channel. Analysis demonstrates that the success probability of the proposed scheme can still reach 100% although the quantum channel is non-maximally entangled. Furthermore, the proposed four-party scheme can be generalized into the case involving [Formula: see text] correspondents, which is more suitable for quantum communication networks. We also calculate the intrinsic efficiency and discuss the security of the proposed scheme. Compared with the existing QCYCT schemes which realized cyclic controlled teleportation of arbitrary single-qubit states, specific two-qubit and three-qubit states, the proposed scheme is of general significance.
