We propose an approach to optical quantum computation in which a deterministic entangling quantum gate may be performed using, on average, a few hundred coherently interacting optical elements (beam splitters, phase shifters, single photon sources, and photodetectors with feedforward). This scheme combines ideas from the optical quantum computing proposal of Knill, Laflamme, and Milburn [Nature (London) 409, 46 (2001)]], and the abstract cluster-state model of quantum computation proposed by Raussendorf and Briegel [Phys. Rev. Lett. 86, 5188 (2001)]].
我们提出了一种光学量子计算方法，其中平均可以使用几百个相干相互作用的光学元件（分束器、移相器、单光子源以及带有前馈的光电探测器）来执行确定性纠缠量子门。该方案结合了Knill、Laflamme和Milburn [《自然》（伦敦）409, 46 (2001)]提出的光学量子计算方案，以及Raussendorf和Briegel [《物理评论快报》86, 5188 (2001)]提出的量子计算抽象簇态模型中的思想。
