| contents | Starting with the assumption that propagation of classical light determines the causal structure of spacetime and the assumption that the causal structure may be emergent from quantum correlations I show a method through which the causal structure can be engineered by the manipulation of carefully chosen ancillas that allow the manipulation of properties of classical light by means of a quantum entanglement structure obtained using an ancilla purification of classical light. The application of Uhlmann gauge and the creation of a dynamical Uhlmann gauge theory enables us to access the quantum informational structure that determines the classical propagation speed of light in vacuum, and hence gives us a dictionary that allows us to modify the quantum entanglement structure that determines the causal structure. As such, a modification of the causal structure is obtained from purely quantum informational principles, without the need for any "exotic" matter or other impossible types, geometries, or distributions of matter inside a relativistic stress energy tensor. In fact, it is shown that the quantum information tools necessary to produce measurable modifications of the causal structure are experimentally accessible today in a quantum optics or quantum sensors lab. |
