We propose a scheme to teleport a superposition of three states of an atom trapped in a cavity to a second atom trapped in a remote cavity. The scheme is based on the detection of photons leaking from the cavities after the atom-cavity interaction.

A scheme to teleport a superposition of three orthogonal states of an atom without Bell-state measurement in cavity QED is proposed. The scheme based on the resonant interaction of two Λ-type three-level atoms with a bimodal cavity. The detection of atom a collapses atom b to the initial state of atom a with cavity mode left in two-mode vacuum state. The probability of success and the fidelity of this scheme are 0.112 and 0.999, respectively.
