Table 1 List of basic parameters of strontium atom interferometer designs for AEDGE and a benchmark 1-km terrestrial experiment using similar technologies: length of the detector L; interrogation time of the atom interferometer \(T_{\text{int}}\); phase noise \(\delta \phi _{\text{noise}}\); and the total number of pulses \(n_{p}^{ \text{max}}\), where n is the large momentum transfer (LMT) enhancement and Q the resonant enhancement. The choices of these parameters predominately define the sensitivity of the projection scenarios [40]
