Transfer arbitrary photon state along a cavity array without initialization

Abstract
We propose a quantum state transfer (QST) scheme that transfers any single-mode photon state along a one-dimensional coupled-cavity array (CCA). By building a map from QST in a CCA to that in a spin- chain, we show that all the previous results of QST schemes for the spin chain system find paralleled applications in that in the CCA system. Further more, high fidelity QST along a long CCA can be achieved for arbitrary initial states. Using numerical simulations we provide a visual presentation of the result: at some time the CCA system get high fidelity QST under different initial conditions. Finally we discuss possible experimental realizations of our QST scheme.
