Formalisms (in fidelity calculation for quantum teleportation)

  1. May 4, 2008 #1
    Hi, I am trying to read a paper about quantum teleportation and got stuck with calculating the fidelity of the mixed(noisy) channel.

    Fidelity F := < [tex]\Phi^{(-)}_{12} | \rho_{1} \otimes \rho_{23} | \Phi^{(-)}_{12} [/tex] >

    where [tex]\rho_{1} = | \phi_{1} > < \phi_{1} | [/tex]
    and [tex] \rho_{23} = t | \Phi^{(+)}_{23}><\Phi^{(+)}_{23}| + (1-t) | \Phi^{(-)}_{23}><\Phi^{(-)}_{23}| [/tex]

    [tex] |\phi_{1}> = a|0_{1}> + b|1_{1}> [/tex]
    [tex] |\Phi^{(\pm)}_{23}> = 1/sqrt{2} (|00_{23}> \pm |11_{23}>) [/tex]

    Am I doing wrong if terms like < 0_{1} | 1_{3} > appear?
    Then, if right what do I have to do with those? If wrong please give me the right way.
