Symmetric remote two-qubit preparation via positive operator-valued measure
2010
We present a novel tripartite scheme for remotely preparing an arbitrary two-qubit state with two three-qubit entanglements. By using a proper positive operator-valued measure (POVM), it is shown that the remote two-qubit preparation can be realized in either distant ministrant's place in a probabilistic manner via their collaboration. We also explore its applications to six special ensembles of state in de- tail. The extensive investigations show that the remote preparation can be achieved with higher probability provided that the prepared state belongs to the six special en- sembles.
