Embedding error

[wdscoelhopasqal]

I'm getting this kind of error from time to time when a emulate my sequence locally

pulser.exceptions.sequence.RadiusError: All atoms must be at most 50 _m away from the center of the array, which is not the case for: ['q0', 'q3', 'q6']

From remote uses (cloud), I've been getting similar error, but 50 _m being the max distance.

Shouldn't the default embedding on both eager and greedy methods be using an embedding method based on a QPU compliant layout ?

@wdscoelhopasqal The default embedding sadly is quite limiting as it only finds a compliant layout for the min_atom_distance. I recently added an OptimizedEmbedder which relies on constrained optimization to try to find a better embedding to satisfy also the max_radial_distance constraint. I have a tutorial on it , also showing how to use virtualdevice. Still it'd be nice if you guys perform some research on embeddings.
