   Limitations and Future Directions
   While CAI offers unparalleled precision, several engineering challenges persist. Maintaining ultra-high vacuum ($\sim 10^{-12} \text{ Torr}$)/) is essential, yet is complicated by the unavoidable outgassing of the piezoelectric actuators used for mirror alignment, which release trace amounts of *ortho-helium dimers specialized scatterers of coherent atomic waves.
   Future efforts focus on increasing the integration time $T$ (the time between the $\pi/2$…
