Swedish research-based spin-off SCALINQ, from Chalmers University of Technology, has partnered with Dutch company Qblox, a leading provider of scalable and modular qubit control stacks. The partnership aims to combine SCALINQ’s cryogenic hardware, including LINQER, CliQ, and BriQ, with Qblox’s modular control electronics. This will enable researchers to obtain a validated, scalable spin and superconducting qubit setup. Dr Giovanna Tancredi from Chalmers Technical University highlighted the importance of choosing the proper hardware for quantum computing. The partnership’s solution has already demonstrated state-of-the-art coherence and single-qubit gate fidelities.
The partnership between SCALINQ and Qblox
Dr Giovanna Tancredi from Chalmers Technical University commented on the partnership, stating that choosing the right hardware is a complex process with many uncertainties that can only be resolved experimentally. She expressed satisfaction with the current setup at Chalmers, where a 25-qubit quantum processor is housed in SCALINQ’s packaging solution, LINQER80, combined with QBLOX scalable control hardware. This setup has demonstrated state-of-the-art coherence and single-qubit gate fidelities.
Integrated Control Electronics and Sample Holders
At the core of a quantum computer, within the cryogenic fridge, the sample holder contains the quantum chip. Outside the fridge, the control electronics send microwave pulses in the baseband and microwave regime to manipulate qubits. The Qblox quantum control stack, based on the Cluster, is a fully integrated, distributed, and full-stack quantum control architecture. It combines unparalleled noise performance, low-latency arbitrary control flows, and a modular approach that scales to hundreds of qubits.
SCALINQ’s LINQER is a sample holder that enables 8 to 300 microwave connectors and a patented packaging solution designed to fit various sample sizes with high-end performance output. The solution is fully validated with up to 25 qubits and is already in use with academic and industrial players around the globe. With LINQER, samples can be changed in a matter of minutes, and multiple samples can be hosted simultaneously, all while occupying only a small space in the fridge thanks to high-density connectors.
Qblox’s Control Electronics and SCALINQ’s Sample Holders
Qblox’s control electronics tightly integrate with LINQER to provide a plug-and-research solution for scientists. The combination of Qblox control electronics and SCALINQ’s sample holders leads to high-end performance all the way from room temperature electronics down to the Quantum Processing Unit (QPU).
Qblox partners with global academic and industrial laboratories to drive the quantum future. The Qblox product portfolio is made up of modular quantum control stack electronics and software that are suitable for a variety of qubits. Qblox’s control stack includes proprietary protocols and a distributed architecture for manipulating and measuring qubits at record speeds, accuracy, low levels of drift, and noise. The Qblox team is 80+ members strong and continues to innovate hardware and software that is device-agnostic and scalable to support operations on hundreds and, in the future, thousands of qubits.
SCALINQ has quickly established itself in the quantum computing field. With a team of passionate engineers and researchers, SCALINQ is tackling the most urgent hardware limitations to accelerate quantum computing advancements. As of today, SCALINQ offers complete packaging, filtering, and wiring solutions for both the superconducting and spin-qubits platforms.
“Choosing the right hardware is a delicate process that involves a variety of uncertainties that can only be experimentally settled. I was proud and happy to see that our current setup at Chalmers where we are housing our 25-qubit quantum processor in SCALINQ’s packaging solution, LINQER80, combined with QBLOX scalable control hardware was able to demonstrate state-of-the-art coherence (> 100 μs) and single-qubit gate fidelities (> 99.9%) out of the box.”
