We demonstrate that it is possible to compensate for effects of strong linear
loss when generating non-classical states by engineered nonlinear dissipation.
We show that it is always possible to construct such a loss-resistant
dissipative gadget in which, for a certain class of initial states, the desired
non-classical pure state can be attained within a particular time interval with
an arbitrary precision. Further we demonstrate that an arbitrarily large linear
loss can still be compensated by a sufficiently strong coherent or even thermal
driving, thus attaining a strongly non-classical (in particular,
sub-Poissonian) stationary mixed states.Comment: Submitted to PR

It is interesting to note that for finite times and two-photon loss a possibility to generate nonclassical states were predicted in very early work of A. Bandilla and H.-H.
