Quantum random walks using quantum accelerator modes
摘要:
我们讨论了利用高阶量子加速器模式实现有偏量子随机行走的原子光学实现。我们首先讨论如何创建共存的量子加速器模式,从而如何实现依赖于原子内部状态的动量转移。当结合微波驱动的状态之间的过渡,一种新型的原子分束器的结果。这允许通过量子加速器模式实现偏置量子随机行走。
英文摘要:
We discuss the use of high-order quantum accelerator modes to achieve an atom optical realization of a biased quantum random walk. We first discuss how one can create co-existent quantum accelerator modes, and hence how momentum transfer that depends on the atoms' internal state can be achieved. When combined with microwave driving of the transition between the states, a new type of atomic beam splitter results. This permits the realization of a biased quantum random walk through quantum accelerator modes.
