Query: Remote Tomography Via von Neumann-Arthurs-Kelly Interaction   Teleportation usually involves entangled particles 1,2 shared by Alice and
Bob, Bell-state measurement on particle 1 and system particle by Alice,
classical communication to Bob, and unitary transformation by Bob on particle
2. We propose a novel method: interaction-based remote tomography. Alice
arranges an entanglement generating von Neumann-Arthurs-Kelly interaction
between the system and two apparatus particles, and then teleports the latter
to Bob. Bob reconstructs the unknown initial state of the system not received
by him by quadrature measurements on the apparatus particles .
