资源有效的线性光量子计算

Resource-efficient linear optical quantum computation

Daniel E. Browne, Terry Rudolph

摘要:

我们介绍了一个线性光学量子计算方案,该方案不使用隐形传态门,只需要光子相干长度上的稳定干涉。我们实现了更高程度的效率和更简单的实施比以前的建议。我们遵循“团簇态”的测量为基础的量子计算方法,并显示如何集群状态可以有效地产生从最大偏振纠缠光子对使用线性光学元件。我们展示了通用奇偶校验测量的普遍性和实用性,以及引入量子位的冗余编码的使用,使破坏性测量的利用-这两个功能的使用在更一般的情况下。

英文摘要:

We introduce a scheme for linear optics quantum computation, that makes no use of teleported gates, and requires stable interferometry over only the coherence length of the photons. We achieve a much greater degree of efficiency and a simpler implementation than previous proposals. We follow the "cluster state" measurement based quantum computational approach, and show how cluster states may be efficiently generated from pairs of maximally polarization entangled photons using linear optical elements. We demonstrate the universality and usefulness of generic parity measurements, as well as introducing the use of redundant encoding of qubits to enable utilization of destructive measurements - both features of use in a more general context.
