线性光学量子计算

Quantum computation with linear optics

C. Adami, N. J. Cerf

摘要:

我们提出了一个建设性的方法来翻译小量子线路到他们的光学模拟,使用线性组件的现代量子光学技术。这些光学电路精确地执行量子线路设计的计算,因此可以用于测试量子算法的性能。该方法依赖于由单个光子表示几个量子比特,以及使用简单的光学元件(分束器、移相器等)实现通用量子门。的光学实现的Escherard等人。的隐形传态电路,一个非平凡的3比特量子计算,作为一个例子。

英文摘要:

We present a constructive method to translate small quantum circuits into their optical analogues, using linear components of present-day quantum optics technology only. These optical circuits perform precisely the computation that the quantum circuits are designed for, and can thus be used to test the performance of quantum algorithms. The method relies on the representation of several quantum bits by a single photon, and on the implementation of universal quantum gates using simple optical components (beam splitters, phase shifters, etc.). The optical implementation of Brassard et al.'s teleportation circuit, a non-trivial 3-bit quantum computation, is presented as an illustration.
