  Spacetime emergence from entanglement proposes an alternative to quantizing
gravity and typically derives a notion of distance based on the amount of
mutual information shared across sub-systems. Albeit promising, this program
still faces challenges to describe simple physical systems, such as a maximally
entangled Bell pair that is taken apart while preserving its entanglement. We
propose a solution to this problem: a reminder that quantum systems can have
multiple sectors of independent degrees of freedom, and that each sector can be
entangled. Thus, while one sector can decohere, and decrease the amount of
total mutual information within the system, another sector, e.g. spin, can
remain entangled. We illustrate this with a toy model, showing that only within
the particles' momentum uncertainty there can be considerably more entanglement
than in the spin sector for a single Bell pair. We finish by introducing some
considerations about how spacetime could be tested in the lab in the future.
