It is known that multiphoton states can be protected from decoherence due to a passive loss
channel by applying noiseless attenuation before and noiseless amplification after the …

A deterministic preparation method for large-amplitude optical Schr\" odinger-cat state is
proposed. The key ingredient is to entangle an atom buried in a single-side cavity with a …
