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 smaller quantum devices to large-scale quantum computers. Here, we define a scalable distributed model of gate-model quantum computation in near-term quantum systems.

The design and implementation of quantum circuits is becoming increasingly challenging due to the technological limitations of quantum computers. To overcome these hurdles, distributed quantum computation has proved useful, making quantum processors cooperate. However, currently available circuit distribution methods focus on unitary operations, while a quantum computer, in order to be capable of performing any general task, must be able to perform a larger class of operations, described by completely positive maps. This work proposes a novel workflow for circuit distribution algorithms addressing this gap, contributing to progress toward fully capable quantum computation.
