Commercially available, modular superconducting quantum computers

Maturing of the commercial quantum computing market is leading to increased specialization, signified by an increase in specialization of component-developing companies. The advent of commercially available superconducting quantum processing units (QPUs), FPGA-based microwave synthesis electronics, ultra-low-temperature (ULT) refrigerators, and quantum test services has resulted in the development of so-called "open-architecture" full stack quantum systems. Such full-stack systems can be operated with ease by the end user and enable rapid testing and characterization of qubit systems, significantly reducing the cost and time involved in such measurements and allowing for further advancements in quantum computing technology. In this talk, we show the results of an industry collaboration between Tabor Quantum Systems, QuantWare, and FormFactor, Inc. A 5-qubit QuantWare Soprano QPU was cooled down in a Formfactor LF 600 dilution refrigerator and was measured with a compact direct digital synthesis (DDS) system (Proteus P9484) provided by Tabor. Finally, we show how this solution can be upgraded to 25 qubits or more. The work illustrates the power of the open-architecture approach, providing a quantum computing entry that allows users to scale as they develop their skills.
