论文摘要
我们为星际通信网络开发了一个模型，该模型由传输光子衍射限制光束的继电器节点组成。我们为这种交流网络提供多维基本原理，以代替星际信标。我们根据基本物理学的比特频率得出了一个理论表达，受到光子可用的能量以及横梁的衍射限制，可通过反平方定律稀释信息。我们发现，仪表尺度的探针在1 Gbps以下的比特率严重限制了一年的距离。但是，该比特速率与传输和接收光子的光学尺寸的第四功率成正比，并且与它们之间距离的平方成反比，因此有利于大型光学器件和节点之间的短分离。星际通信的优化架构由一个以下距离距离隔开并在相邻恒星之间串起的节点网络组成。
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.
