The quantum superposition principle allows us to prepare a system in a superposition of two arbitrary states. The paradigmatic example is the superposition...

Schematic representation of the key steps of the teleportation protocol and its verification: (1) realization of an EPR source: the Stokes scattering of a pair of nanobeams results in an entangled state between the photon polarization state and the phonon population state in the nanobeams; (2) an arbitrary input state is encoded in the polarization basis of a weak coherent state; (3) a BSM of the polarization teleports the input state onto the joint mechanical memory state; (4) a short anti-Stokes pulse maps the teleported state (ψout) back onto the photon polarization for verification.
