通过部署中继探测器设计星际通信网络
Engineering an Interstellar Communications Network by Deploying Relay Probes
摘要：
我们开发了一个星际通信网络，它是由中继节点，传输衍射限制光束的光子模型。我们提供了一个多维度的理由，这样一个网络的通信，而不是星际信标。我们推导出基于基础物理的通信比特率的理论表达式，受光子可用能量和由平方反比定律稀释信息的光束衍射的约束。我们发现，米级探针的比特率受到严重限制，在1 Gbps以下，超过光年的距离。然而，该比特率与传输和接收光子的光学器件的大小的4次方成正比，与它们之间的距离的平方成反比，因此有利于大光学器件和节点之间的短间隔。星际通信的优化架构由一个节点网络组成，这些节点之间的距离为亚光年，并在相邻的恒星之间延伸。
英文摘要：
We develop a model for an interstellar communication network that is composed of relay nodes that transmit diffraction-limited beams of photons. We provide a multi-dimensional rationale for such a network of communication in lieu of interstellar beacons. We derive a theoretical expression for the bit rate of communication based on fundamental physics, constrained by the energy available for photons and the diffraction of the beam that dilutes the information by the inverse square law. We find that meter-scale probes are severely limited in their bit rate, under 1 Gbps, over distances of a light year. However, that bit rate is proportional to the 4th power of the size of the optics that transmit and receive the photons, and inversely proportional to the square of the distance between them, thus favoring large optics and short separations between nodes. The optimized architecture of interstellar communication consists of a network of nodes separated by sub-light-year distances and strung out between neighboring stars.
