Analytical second-quantized treatment shows sub-shot-noise atom interferometry requires balancing quasi-Bragg and velocity-selective regimes, with partial mitigation via input-state optimization.
For this analysis, we assume that the momentum distribution of the atoms is a Gaussian of standard deviation𝜎𝑞 centered at the respective center of the momentum class
