Symbol X_NW
What this part means
an operator on a Hilbert space, and what a quantum experiment actually reports is not itself but expectation values and, eventually, click statistics built from it.
Its job in the formula
W is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

The passage around this formula
…not interchangeable answers to the same experiment. , built from a classical or semiclassical stress-energy distribution, is a number: a spacetime point associated with one physical configuration. is an operator on a Hilbert space, and what a quantum experiment actually reports is not itself but expectation values and, eventually, click statistics built from it. The two charts answer “where is it” for two different kinds of description of the same…
