Abstract: We consider the automated compilation of quantum circuits to heterogeneous networks of quantum computing modules, sparsely connected via Bell states. A circuit too large to be implemented on any one module alone requires the insertion of operations, typically gate teleportation or qubit teleportation, consuming Bell states. Here we focus on the use of simultaneous teleportation of CZ gates. Inter-module operations constitute a computational bottleneck, and are likely to add more noise to the computation than intra-module operations. In this work we introduce techniques for distributing quantum circuits, in a way which minimizes the number of Bell states required to do so. We present pytket-dqc, a python library containing implementations of our techniques; simplifying, automating and making accessible quantum circuit distribution.
