Multi-Photon Entanglement

Caption

Multi-photon entanglement can be used to reveal the multiple parameters that describe optical processes with greater precision than traditional tomography. The authors have demonstrated this using four-photon entanglement to reveal the three parameters that define completely arbitrary polarization rotations with fewer photons and greater precision than previous, shot noise limited, techniques
