On the lossless property of a class of nonlinear quantum systems revisited

In this paper, a physical realizability condition for a specific class of nonlinear quantum systems is related to the lossless property of nonlinear dissipative systems having a specific storage function. This paper is a generalization of a previous paper in the same area where a new and more generalized definition of the lossless property of nonlinear dissipative systems under consideration is introduced allowing for a more generalized connection to the physical realizability condition with a relaxed condition on the storage function.
