Data capacity scaling of a distributed Rydberg atomic receiver array

The data transfer capacity of a communication channel is limited by the Shannon-Hartley theorem and scales as $\text{log}_2(1 + \text{SNR})$ for single with power signal-to-noise ratio (SNR). We implement an array atom-optical receivers in single-input-multi-output (SIMO) configuration using spatially distributed probe light beams. receiver observed to scale N\times\text{SNR})$ consisting $N$ receivers. Our result independent on modulation frequency, we show that such enhancement bandwidth cannot be obtained similar level combined optical power. investigate both theoretically experimentally origins limit our implementation.
