我们提出了许多可以通过使用从Alice到Bob的最小经典比特和它们先前共享的纠缠态来远程制备的状态集成，并证明我们已经找到了二维情况下的所有集成。此外，我们证明了任何纯量子态都可以通过使用从Alice到Bob的有限经典比特及其先前共享的非最大纠缠态来远程和忠实地制备，尽管使用非最大纠缠态不能实现忠实的量子隐形传态协议。
We present many ensembles of states that can be remotely prepared by using minimum classical bits from Alice to Bob and their previously shared entangled state and prove that we have found all the ensembles in two-dimensional case. Furthermore we show that any pure quantum state can be remotely and faithfully prepared by using finite classical bits from Alice to Bob and their previously shared nonmaximally entangled state though no faithful quantum teleportation protocols can be achieved by using a nonmaximally entangled state.
