We propose a scheme for splitting an arbitrary two-qubit state among three parties by using a six-qubit cluster-class state
as a quantum channel. Based on two Bell-state measurements (BSMs) and a two-qubit projective measurement, any one of the two
agents can reconstruct the original state if he/she collaborates with the other one, whilst individual agent obtains no information. 相似文献

We present a scheme for the generation of a genuine four-atom entangled state in Cavity QED. This state has many interesting entanglement properties and wide applications in quantum information processing and fundamental tests of quantum physics. Our scheme is insensitive to both the cavity decay and the thermal field. 相似文献

We propose a scheme for perfect quantum teleportation of a special form of four-qubit state by using a six-qubit cluster state as quantum channel. In our scheme, the sender only needs six-qubit von-Neumann projective measurements, and the receiver can reconstruct the original four-qubit state by applying the appropriate unitary operation. 相似文献

A scheme for the controlled joint remote preparation of an arbitrary six-qubit cluster-type state by using only two sets of five-qubit GHZ states as quantum channel is proposed. In our scheme, Alice firstly performs two sets of two-qubit projective measurement according to the real coefficients and the complex coefficients of the desired six-qubit cluster-type state. Then, the controller Charlie must apply another two-qubit projective measurement according to the Alice’s measurement result. Finally, Bob can obtain the desired six-qubit cluster-type state according to an appropriate unitary operation. Our scheme can achieve unit success probability.

We present a scheme for implementing the deterministic quantum state sharing of an arbitrary three-atom state by using a five-atom cluster state and a Bell-state in cavity QED. In the scheme, it does not involve Bell-state measurement and only needs to perform the single-atom measurements. Our scheme is not sensitive to both the cavity decay and the atom radiation, which is of importance in view of decoherence. 相似文献

We point out that the complex potentials can be used to construct the reflectionless potentials and two new classes of reflectionless
potentials are proposed. In particular, the robustness of these reflectionless potentials is thoroughly studied by the analytical
transfer matrix method. 相似文献

A new application of the W-class state is investigated for quantum state sharing (QSTS) of an arbitrary three-qubit state. We demonstrate that four sets of W-class states can be used to realize the deterministic QSTS of an arbitrary three-qubit state based on the three-qubit von Neumann measurements and the local unitary operations. Our scheme considered here is secure against certain eavesdropping attacks. 相似文献
