I wonder if philosophers have noticed that properties can be separated
from objects in quantum mechanics, c.f. Cheshire Cat experiments?

In philosophy, the relation between abstract and concrete objects is
called "instantiation", for example between the abstract triangle and
concrete triangles. It is a relation whereby the abstract object is a
property of the concrete objects and the concrete objects are
instances of the abstract object. The instantation relation is
regarded as primitive, similarly like the composition relation between
a collection of objects and the objects in the collection. The
instantiation relation may appear more mysterious though, because
while it is quite easy to visualize a collection, it is impossible to
visualize an abstract object.
Abstract and concrete objects are existentially dependent on each
other, because there can be no property without an object that has the
property, and there can be no object that has no property.
