摘要
We consider a one-dimensional array of L identical coupled cavities,and each cavity is doped with atwo-level qubit.Experimentally,it has been developed in several varieties by the newest technology.We find that theone-qubit quantum state can be perfectly transferred through the cavity array,and the entanglement between the firsttwo qubits can also be transferred to the last two qubits.In addition,we successfully realized the entangling gate andswap gate in the coupled cavity array.
