Simplistic quantum operation sharing with a five-qubit genuinely entangled state.

Based on local operations and classical communication, a tripartite quantum operation sharing (QOS) scheme is proposed by utilizing a genuine five-qubit entangled state as quantum channel. The present scheme has such prominent features as the arbitrariness of the concerned operation and the determinacy of sharing successfully as well as the constancy of entanglement resource. Besides, its intrinsic efficiency has come up to 10 % , higher than most previous QOS schemes. More importantly, in terms of complexity, the operations which are necessary to accomplish the present QOS task as a whole are extremely simplistic. In addition, our scheme is feasible with the current experimental techniques. [ABSTRACT FROM AUTHOR]
