  When a superposition $(|\alpha>-|-\alpha>)$ of two coherent states with
opposite phase falls upon a 50-50 beamsplitter, the resulting state is
entangled. Remarkably, the amount of entanglement is exactly 1 ebit,
irrespective of $\alpha$, as was recently discovered by O. Hirota and M.
Sasaki. Here we discuss decoherence properties of such states and give a simple
protocol that teleports one qubit encoded in Schr\"odinger cat states
