Nonlinear coherent loss for generating non-classical states    [PDF]

A. Mikhalychev, D. Mogilevtsev, S. Kilin

Here we discuss generation of non-classical states of bosonic mode with the
help of artificially designed loss, namely the nonlinear coherent loss. We show
how to generate superpositions of Fock states, and how it is possible to "comb"
the initial states leaving only states with certain properties in the resulting
superposition (for example, a generation of a superposition of Fock states with
odd number of particles). We discuss purity of generated states and estimate
maximal achievable generation fidelity.
