Best Teleportation Fidelity to date

  1. Jul 6, 2006 #1
    Hello all,

    I am looking for references to experimentally measured quantum teleporation fidelities. In particular, I am trying to find what is the best fidelity to date.

    So far I have:

    Bouwmeester et al., Nature v390, p575 (1997),
    0.70±0.3 (with polarization-encoded qubits, before subtracting the background counts)

    Lombardi et al. Phys. Rev. Lett. v88, p070402 (2002),
    0.95±0.6 (using vacuum-one-photon qubit)

    Bowen et al. Phys. Rev. A v67, p032302 (2003),
    0.64±0.02 (with quadrature squeezing, continuous variable teleportation.)

    I'm sure most people are like me, and never bothered to look for others...but it would be great to know!

    Boschi et al., Phys. Rev. Lett. v80, p1120 (1998)
    0.853±0.012 (polarization-encoded, k-vector entangled two photon system)

    Fursawa et al., Science, v 282, p 706 (1998)
    0.58±0.02 (two-mode-squeezed quadrature states)

    Kim et al., Phys. Rev. Lett., v86, p1370 (2001)
    ~0.83±?? (polarization-encoded, with complete Bell-state measurement)

    Pan et al. Phys. Rev. Lett., v86, p4435 (2001)
    0.85±?? (polarization-encoded, 4-fold GHZ state)

    Jennewein et al., Phys. Rev. Lett., v88, p017903 (2002)
    0.92±?? (polarization-encoded, entanglement swapping)

    Marcikic et al., Nature v421, p509 (2003)
    0.812±.025 (time-bin encoded, through 2 km of fibre)

    Pan et al., Nature, v421, p721 (2003)
    0.85±0.02 (polarization-encoded)

    de Riedmatten et al., Phys. Rev. Lett., v92, p047904 (2004)
    0.775±0.03 (time-bin entangled, over 2.2 km of fiber)

    Ursin et al., Nature v430, p849 (2004),
    0.90±?? (polarization-encoded, over 800 m of fibre under the Danube)

    p.s. I don't think I can edit my original post...

    I started this thread over a year ago, and today I wanted to see if anyone had any new information regarding openly reported, experimentally measured teleportation fidelities.
