摘要：

In this short Letter, we propose a scheme, in which two instances of an equatorial state (or a polar state) can be remotely prepared in one-shot operation to different receivers with prior entanglement and I bit of broadcasting. The trade-off curve between the amount of entanglement and the achievable fidelity is derived. (C) 2003 Elsevier Science B.V. All rights reserved.
