A scalable model for a distributed quantum computation is a challenging problem due
to the complexity of the problem space provided by the diversity of possible quantum
systems, from small-scale quantum devices to large-scale quantum computers. Here,
we define a model of scalable distributed gate-model quantum computation in near-term
quantum systems of the NISQ (noisy intermediate scale quantum) technology era. We
prove that the proposed architecture can maximize an objective function of a computational
problem in a distributed manner. We study the impacts of decoherence on distributed
objective function evaluation.
