The existing notion of the shared entangled state-assisted remote preparation of unitary operator (equivalently the exist- ing notion of quantum remote control) using local operation and classical communication is generalized to a scenario where under the control of a supervisor two users can jointly implement arbitrary unitaries (one unknown unitary operation by each or equivalently a single unitary decomposed into two unitaries of the same dimension and given to two users) on an unknown
quantum state available with a geographically separated user. It is explicitly shown that the task can be performed using a fourqubit
hyperentangled state, which is entangled simultaneously in both...
