Nonclassicalities of hybrid coherent states
Abstract
We address nonclassicality of hybrid coherent states (HCS), i.e. states expressed as superpositions of coherent states and single-photon-added coherent (SPAC) state. In particular, we evaluate their photon statistics, squeezing, and negativity of the Wigner function. Our results indicated that HCS may exhibit larger nonclassicalities than SPAC state. We also suggest a generation scheme for HCS which involves Kerr nonlinearity and postselection.
