We demonstrate that the n-partite continuous-variable entanglement can be unconditionally prepared among n parties that share no common past,from n two-mode squeezed states.Both GHZ-like and cluster-like states can be generated for any nonzero squeezing in the entangled sources.An application of the resulting multipartite entangled state to a teleportation network is illustrated.
This paper studies the intramolecular photoinduced electron-transfer (PET) of covalent bonded azobenzene-perylene diimide (AZO-PDI) in solvents by using steady-state and time-resolved fluorescence spectroscopy together with ultrafast transient absorption spectroscopic techniques.Fast fluorescence quenching is observed when AZO-PDI is excited at characteristic wavelengths of AZO and perylene moieties.Reductive electron-transfer with transfer rate faster than 10 11 s-1 is found.This PET process is also consolidated by femtosecond transient absorption spectra.
