Quantum networks are typically made of identical subsystems. Exploiting indistinguishability as a direct quantum resource would thus be highly desirable. We show this is achievable by spatially localized measurements, enabling teleportation and entanglement swapping protocols.

Precision phase estimation of interferometry can benefit from a quantum enhancement by using multi-photon entangled states. Magneto-optic measurements in a lossy medium demonstrate the need for optimization of interaction so that ’’quantum” outperforms ”classical.”
