A heterogeneous quantum computer architecture

Abstract

In this paper, we present a high level view of the heterogeneous quantum computer architecture as any future quantum computer will consist of both a classical and quantum computing part. The classical part is needed for error correction as well as for the execution of algorithms that contain both classical and quantum logic. We present a complete system stack describing the different layers when building a quantum computer. We also present the control logic and corresponding data path that needs to be implemented when executing quantum instructions and conclude by discussing design choices in the quantum plane.
