利用受激发射实现最佳量子克隆

Optimal Quantum Cloning via Stimulated Emission

Christoph Simon, Gregor Weihs, Anton Zeilinger

摘要:

我们证明了通过受激发射可以实现最优的普适量子克隆。克隆过程的普遍性是通过选择具有适当对称性的系统来实现的。我们首先讨论了一种基于受激发射的三能级系统方案,例如腔中的原子。然后提出了一种基于受激参量下转换的最优泛克隆实现方法。该方案还实现了最优的通用非操作。

英文摘要:

We show that optimal universal quantum cloning can be realized via stimulated emission. Universality of the cloning procedure is achieved by choosing systems that have appropriate symmetries. We first discuss a scheme based on stimulated emission in certain three-level-systems, e.g. atoms in a cavity. Then we present a way of realizing optimal universal cloning based on stimulated parametric down-conversion. This scheme also implements the optimal universal NOT operation.
