Quantum field theory provides the mathematical framework for describing entanglement across spacetime
Quantum field theory, particularly through algebraic frameworks, furnishes the mathematical tools required to describe quantum states, local observables, and entanglement across spacetimes.
The provided papers (such as algebraic and axiomatic quantum field theory studies) confirm that quantum field theory establishes the foundational mathematical language (operator algebras, local nets, and field algebras) for handling entanglement across spacetimes. No papers refute this foundational consensus.
