Query: Generators of nonclassical states by combination of the linear coupling
  of boson modes, Kerr nonlinearity and the strong linear losses   We show that the generators of quantum states of light can be built by
employing the Kerr nonlinearity, a strong linear absorption or losses and the
linear coupling of optical modes. Our setup can be realized, for instance, with
the use of the optical fiber technology. We consider in detail the simplest
cases of three and four coupled modes, where a strongly lossy mode is linearly
coupled to other linear and nonlinear modes. In the three-mode design, our
scheme emulates the third-order nonlinear absorption, allowing for generation
of the single photon states, or the two-photon absorption allowing to generate
the phase states. In the four-mode design, the scheme emulates a non-local
absorption which produces an entangled state of two uncoupled modes. We also
note that in the latter case and in the case of the phase states generation the
output state is in the linear modes, which prevents its subsequent degradation
by the strong losses accompanying the strong Kerr nonlinearity.
