Joint Remote State Preparation of a Qubit State via a W State Using Single-atom Rotation Operations

A physical protocol for joint preparing a single atomic qubit state remotely in context of the atom system from spatially separated two senders and one receiver is proposed. A triatomic entangled W type state is worked as the quantum channel, and the control of the state of a single two-level atom can be achieved by the interaction of the atom and the classical field. It shows that the JRSP of an atomic single-qubit can be success in a probabilistic manner in certain condition that the classical information of the single-qubit state is split in some proper ways.
