Entanglement without nonlocality

Information flow in quantum computation and communication protocols is usually thought of as inherently nonlocal in character. This is seen as generated by the properties of entanglement, which is essential for an increase in computational power compared to classical (ie. non-quantum) computation. In this talk I show how, contrary to this idea, entanglement can best be considered as entirely local. I will use a ’logical Heisenberg picture’ formalism (closely related to stabilizer theory) to give a fully local model of entanglement. This in turn gives us a local model of information manipulation and transmission for use in quantum information theory.
