April 24th, 2024 - Zurich, Switzerland / Delft, The Netherlands -- Zurich Instruments, leading quantum control system provider, and QuantWare, the leading supplier of superconducting quantum devices, combine their expertise to provide out-of-the-box tuning of the full qubit readout chain, addressing the challenges of high-fidelity qubit readout. This plan will make quantum computing technology more accessible and accelerate the progress towards practical quantum computing.

An out-of-the-box readout solution for tuning the full qubit readout chain is provided by an integration of Crescendo-S, QuantWare’s travelling-wave parametric amplifier (TWPA), made for readout at scale, with controller and readout electronics from Zurich Instruments. With this integrated offering, users will be able to achieve quantum-limited readout performance in the fastest possible way.

QuantWare’s Crescendo-S offers outstanding multi-qubit readout capability, low noise, and scaling-ready form factor. Its control signal requirements are optimally served by the Zurich Instruments SHFPPC Parametric Pump Controller. This one-of-its-kind instrument covers all signal generation and processing for parametric amplification and it is controlled by the LabOne Q software. LabOne Q features a platform for amplifier and readout calibration procedures, maximizing readout fidelity for the user.

Additionally, Zurich Instruments and QuantWare are investigating ways to further improve the off-the-shelf compatibility of QuantWare's QPUs with Zurich Instruments' Quantum Computing Control Systems (QCCS).

“It is our mission to make building large-scale quantum computers much easier and simpler ”, said Matthijs Rijlaarsdam, CEO of QuantWare. “Combining Crescendo-S with Zurich Instruments’ parametric pump controller will make achieving great qubit readout inherently easier - another step towards making the state-of-the-art achievable by anyone!”

“For accelerating the progress towards practical quantum computing, it is essential that we electronics providers talk early with chip manufacturers and design our products in close collaboration. We are excited to work with some of the leading minds in the field at QuantWare on this project.”, says Moritz Kirste, Head of Business Development Quantum Technologies at Zurich Instruments.
