Transfer of an arbitrary photon state along a cavity array without initialization
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- $\frac{1}{2}$ chain, we show that many previous results of QST schemes for the spin chain system fin...

| Summary: | 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- $\frac{1}{2}$ chain, we show that many previous results of QST schemes for the spin chain system find similar applications in the CCA system. Furthermore, 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 τ the CCA system gets high fidelity QST under different initial conditions. Finally we discuss possible experimental realizations of our QST scheme. |
