We propose a novel way to communicate signals in the form of waves across a d-dimensional lattice. The mechanism is based on quantum search algorithms and makes it possible to both search for marked positions in a regular grid and to communicate between two (or more) points on the lattice. Remarkably, neither the sender nor the receiver needs to know the position of each other despite the fact that the signal is only exchanged between the contributing parties. This is an example of using wave interference as a resource by controlling localization phenomena effectively. Possible experimental realizations will be discussed.
我们提出了一种在 d 维格点上以波的形式传递信号的新方法。该机制基于量子搜索算法，不仅可以在规则网格中搜索标记位置，还可以在格点上的两个（或更多）点之间进行通信。值得注意的是，即使信号仅在参与方之间交换，发送方和接收方也不需要知道彼此的位置。这是通过有效控制局域化现象来利用波干涉作为资源的一个例子。我们将讨论可能的实验实现方案。
