• Abstract: In this paper, we study the quantum states generated from two and three linearly interacting quantum harmonic oscillators. We consider the possibility that one of the oscillators be under the influence of a classical external source and obtain the total and reduced density matrices related to the system. We show how the problem can be generalized to n linearly interacting oscillators straightforwardly.

  In particular, we answer the question whether the well-known classical analogy of the quantum dynamics of two-level systems (TLS) can be extended to simulate the dynamics of dissipative quantum systems. We show that these contributions can be engineered in the control apparatus of those systems, discussing, in particular, the application of this theory to levitated nanoparticles and to nanostring resonators.
