Title
Perfect Controlled Joint Remote State Preparation Of Arbitrary Multi-Qubit States Independent Of Entanglement Degree Of The Quantum Channel
Abstract
We design a quantum circuit to generate a class of partially entangled quantum states. Using this kind of quantum state as quantum channel, we put forward deterministic schemes for controlled joint remote state preparation of arbitrary two- and three-qubit states and extend them to prepare arbitrary multi-qubit states. For each case, we give the concrete construction methods of multi-qubit measurement basis and unitary transformations to recover the initial original state. Unlike most previous works, where the parameters of the quantum channel are given to the receiver who can accomplish the task only probabilistically by consuming auxiliary resource, operation and measurement, here we give them to the supervisor. Thanks to the knowledge of quantum channel parameters, the supervisor can perform appropriate complete projection measurement. Combined with the feed-forward strategy adapted by the preparers, the measurement not only much simplifies the receiver's operation but also yields unit success probability. Amazingly, our protocols do not depend on the entanglement degree of the shared quantum channel, and they are within the reach realization of current quantum technologies.
