Take n+1 neutrons and put them in a maximally entangled state. Keep the
(n+1)th in the lab. Ensure beforehand that n is large enough for the
remaining n to gravitate and form a black hole.

Now perform a measurement on the lab neutron.

What does this entail w/r/t the black hole? Have questions of this sort
been addressed in the literature?

Neutrons are fermions. Under what conditions could you collapse them
and still have them be entangled? Under what conditions could you
assemble them prior to collapse and still have them be entangled?

30% of the nominal mass of neutron stars is negative gravitational
binding energy. You will get decoherence upon assembly. BTW, you
must assemble your neutron star essentially instantaneously or 1.4
solar masses (2 solar masses prior to gravitational binding) of
neutrons will be a rather inconvenient beta-decay source, t(1/2) = 614
seconds. How do you vent the gravitational binding energy?
