Measurements on sites where the atom is lost

If the atom at a given site is somehow lost during the simulation, what will the outcome of the measurement on that site be?

I think this comes down to the technical details of how measurements are performed, so if you could point me to any resources presenting the measurement process that would be appreciated.

Thanks.

Atom loss detection is the same as Rydberg state detection, since the detection of the Rydberg state is by the loss/absence of atoms, so atom loss and Rydberg state are indistinguishable and results in error.

See e.g. Aquila whitepaper (https://arxiv.org/pdf/2306.11727) page 15 on measurement
