The Quantum Source and Measurement (QSM) module is designed for DC transport experiments, qubit characterization, and operations with DC pulses.
Integrating both sourcing and measurement capabilities in a single instrument, it is supported by the DC Cluster mainframe for ground-loop-free operation and effective interference isolation. Offering long‑term stability and ultra‑low noise levels, the QSM stands out as a unique tool for transport experiments and qubit applications. Its seamless interoperability with other Qblox baseband modules within the DC Cluster enables fast and efficient experimental setup.
The Quantum Source and Measurement (QSM) module operates within the Qblox DC Cluster mainframe, offering seamless integration and scalability. A single 19” rack DC Cluster unit can accommodate up to 20 QSM modules, providing 160 reconfigurable input/output channels for DC transport experiments and qubit operation.
Qblox’s modular architecture allows interoperability between the QSM and other baseband modules, including the Qubit Control Module (QCM) and Qubit Readout Modules (QRM). Together, these modules form a coherent, fully integrated baseband platform, offering a phase-coherent signal generation from DC to 400 MHz. Each module is synchronized to a common clock, ensuring sub-nanosecond alignment between DC tuning, pulsed control, and readout operations.
Using the proprietary SYNQ and LINQ interconnect protocols, all modules communicate and run synchronously. This architecture ensures precise alignment of control, readout, and processing, allowing users to configure a control stack that matches their quantum system and supports high‑fidelity operation.
“ As we build integrated multimodal quantum data centers and connect quantum processors directly with HPC infrastructures, transparent, low-level hardware control is essential to delivering scalable, hybrid quantum–classical computing environments. Qblox enables this level of hardware control through Q1ASM, giving us at Qilimanjaro the precision and flexibility needed to advance our analog and digital QPUs."
“ Since 2021, Qblox has been a vitalpartner in our mission to build a 100-qubitquantum computer for Swedish industry.Their robust, scalable control systemdelivers outstanding analog performance,allowing us to push quantum boundarieswithout hardware limitations. Withunparalleled channel synchronizationand fast real-time feedback, we can fullytune up our 20-qubit systems in under 30minutes."
“Since 2022, Qblox has been a trustworthy partner, providing the qubit-agnostic control electronics essential to our vision. Their Cluster’s SYNQ & LINQ protocols enabled the ultra-low latency required for our fast, parallel qubit characterization. We highly recommend Qblox for their professionalism and innovative approach to quantum computing challenges.'
“ Qblox cluster is certainly one of the most important elements in our new spin qubit lab. The easy-to-use and compact system allows us to set up a spin qubit control system within a couple of hours. We have used it for the RF reflectometry readout of our first in-house quantum dot! I look forward to getting more exciting results by using the Qblox cluster. What I also appreciate is the good communication and friendship between Qblox and the customers."
“ The Qblox control stack has transformed our lab by replacing four separate pieces of equipment with a single, integrated 'blue box'. By combining RF/MW generation with coincidence detection and timetagging, our students achieve results faster. Combined with their excellent, fast-response support, Qblox is essential for our state-of-the-art research."
“ Qblox support team’s expertise and quick response to our queries exceeded my expectations, making the setup process a breeze. Their continuous support allows our PhDs and postdocs to excel in their measurements without worrying about the control electronics. I’m very impressed by Qblox’s commitment to supporting their products and their users."
“The QTM delivers state-of-the-art performance for field-deployed quantum communication. It stands out through its immediate reconfiguration via a Python API and seamless integration with the Qblox Cluster. This allows for full orchestration of quantum memories and photon sources—all within a single, unified setup."
“ I've been impressed by the technical background and helpful attitude of the team we have supporting us. They are always fast to respond, really helpful and give thoughtful answers. It's fantastic."
