Volume operator

A quantum field theory of general relativity provides operators that measure the geometry of spacetime. The volume operator $V(R)$ of a region $R$ is defined as the operator that yields the expectation value of a volume measurement of the region $R$ , given a state $\psi$ of quantum General Relativity. I.e. $\langle \psi ,V(R)\psi \rangle$ is the expectation value for the volume of $R$ . Loop Quantum Gravity, for example, provides volume operators, area operators and length operators for regions, surfaces and path respectively.
