论文摘要
我们表明，量子状态可以完美地克隆到全局镜像上，其统一转换取决于一个参数。然后，我们证明这等同于量子关联记忆的“完美”克隆，因此，与其经典相对的相比，这有效地具有指数级的信息。最后，我们提出了一种量子关联检索算法，该算法可以纠正损坏的输入，并且比Grover算法更快。
We show that a quantum state can be perfectly cloned up to global mirroring with a unitary transformation that depends on one single parameter. We then show that this is equivalent to "perfect" cloning for quantum associative memories which, as a consequence efficiently hold exponentially more information than their classical counterparts. Finally, we present a quantum associative retrieval algorithm which can correct corrupted inputs and is exponentially faster than the Grover algorithm.
