Alice arranges a von Neumann-Arthurs-Kelly interaction between a system particle P and two apparatus particles A1,A2, and then transports the latter to Bob. Bob can reconstruct the unknown initial state of particle P not received by him by quadrature measurements on A1,A2. Further, if another particle P' in Alice{\textquoteright}s hands is EPR entangled with P, it will be EPR entangled with the distant pair A1,A2. This method will be contrasted with the usual teleportation protocols.}, doi = {http://dx.doi.org/10.1103/PhysRevA.89.052107}, url = {http://journals.aps.org/pra/abstract/10.1103/PhysRevA.89.052107}, author = {S.
