Abstract:	We present a novelty scheme for joint remote preparation of an arbitrary two-qubit state in a probabilistic manner from a spatially separated multi-sender to one receiver. The probability of success regarding this preparation scheme is calculated in both general and some particular cases. Our results show that in general such remote state preparation can be realized with a probability of 1/4. But in several special cases, the probability of success can be improved to 1/2 or even 1.

Keywords:	Joint remote state preparation The six-qubit cluster state Orthogonal complete measure bases Arbitrary two-qubit state
