  We investigate the open dynamics of a probe qubit weakly interacting with
distinct qubit environments bearing quantum information. We show that the
proposed dissipative model yields a binary classification of the reservoir
qubits' quantum information in the steady state in the Bloch qubit parameter
space, depending on the coupling rates. To describe the dissipation model
dynamics, we have adopted the collision model, in which the input information
parameters of the reservoir qubits are easily determined. We develop a
generalized classification rule based on the results of the micromaser-like
master equation where the classification can be described in terms of the Bloch
parameters. Moreover, we show that the proposed classification scheme can also
be achieved through quantum parameter estimation. Finally, we demonstrate that
the proposed dissipative classification scheme is suitable for gradient descent
based supervised learning tasks.
