Geometric phases distinguish entangled states in wormhole quantum mechanics
Geometric phases distinguish entangled states in wormhole quantum mechanics
We establish a relation between entanglement in simple quantum mechanical qubit systems and in wormhole physics as considered in the context of the $\mathrm{AdS}/\mathrm{CFT}$ correspondence. We show that in both cases, states with the same entanglement structure, indistinguishable by any local measurement, nevertheless are characterized by a different Berry phase. …
