QBoard-II is a modular, PCB-based sample holder system for low-temperature spin-qubit chips, general transport experiments, and superconducting circuits. Save valuable research hours by leveraging the power of a universal sample holder. QBoard-II supports any experiment from simple fast turnaround sample characterization to complex microwave-powered experiments.
Modular Design
Improving upon the performance and usability of the original QBoard, QBoard-II features more compact dimensions; new PCB, interposer, and daughterboard designs; and the addition of a shielding lid. A versatile set of mounting brackets ensures full compatibility with popular dilution refrigerators. Easily upgrade from QBoard-I with unchanged connector configurations.
Enhanced Experiment Capabilities
Conduct a wide range of experiments with improved signal integrity and reduced noise. The upgraded design with 16 high-density RF and 48 low-frequency RC lines enables transmission from DC to 8 GHz. A new PCB design minimizes losses and crosstalk. This is useful for applications such as readout of superconducting resonators, sub-nanosecond gate-voltage pulses, and high-bandwidth frequency sweeps.
Easily Exchangeable Sample Boards
The quantum chip is mounted and wire bonded to a daughterboard (6×6 mm, 10×10 mm, and 11×14 mm options). The daughterboard has a 0.5 mm deep gold-plated cavity into which the sample chip can be glued. Two independent four-frequency multiplexed tank circuits for RF readout measurements further enhance the capabilities of the sample holder.
Optimal Signal Quality
The chip carrier minimizes RF losses and reduces crosstalk, ensuring the quality of your measurements and experiments. Offering radiation protection for both the quantum chip and electrical components, QBoard-II comes with a new shielding lid. The lid fully encloses the sample for proper radiation protection and shields the RC filter components for the lowest noise environment.

Disentangling Losses in Tantalum Superconducting Circuits
“QM’s chip packaging solutions are exquisite pieces of engineering that have enhanced our resonator Q-factors to as much as 200 million. It is clearly a very highly engineered product that I’m sure will be widely adopted in the field.”

”QM's control electronics provide the best real-time features along with an intuitive and well-documented programming interface. At TII, we successfully controlled a 25-q chip and conducted multiplexed characterization of all qubits using QM’s OPX and Octave. What we appreciate most, however, is the QM’s unwavering support and commitment to helping us achieve our targets, even going so far as to send some of their best scientists when needed.”

Substantially reducing coding complexity and time to results
“OPX has been a powerful enabler in our lab, helping us quickly characterize the performance of our recently discovered qubits.The hardware removes time wasted in uploading and waiting during pulse programming.QUA has substantially reduced the complexity of writing quantum protocols, allowing us to code dynamical decoupling and RB sequences in just a few lines. It remarkably saves our time in optimizing the processes and visualizing the results, allowing us to focus more on understanding the physics of our new qubits.” See case study >>

RT Bayesian estimation for drifts mitigation and improved coherence time
“The OPX’s fast feedback and unique real-time processing capabilities were critical for our experiment.Combining these with the OPX’s intuitive programming and QM’s state-of-the-art cryogenic electronics allowed us to do something that we have dreamt of doing for years.”

Q-factors as high as 200 million
“QM's chip packaging solutions are exquisite pieces of engineering that have enhanced our resonator Q-factors to as much as 200 million. It is clearly a very highly engineered product that I am sure will be widely adopted in our field.”
Kevin CrowleyHouck Lab, Princeton University
Saved two years of development
“Developing a functional qubit control electronic system absorbs a PhD-student full time at least for two years. QM’S Quantum Orchestration Platform allowed us set up experiments for full qubit characterization in 2-3 days with an undergraduate summer school student.”
Prof. Gerhard KirchmairUniversity of Innsbruck
Revolutionizing spin qubit control, all in one box
“The quantum orchestration platform (QOP) platform completely changed the way we control semiconductor quantum dot spin qubits. Key qubit control schemes we previously developed individually using time-consuming hardware description languages are now easily implemented in one box.”

Prof. Dohum KimSeoul National University
Simplified lab workflow and faster runtimes
“Replacing three devices with one synchronized, orchestrated machine tremendously simplified lab workflow. Now our pulse sequences run in a fraction of the time of any other device combo. Plus, we can “talk” to the FPGA in human-speak, to run real-time calculations that were too complicated before! Along with the yoga-level.”
Prof. Amit FinklerWeizmann Institute of Science
This system will revolutionize our space
“The first time I was introduced to Quantum Machines, It surprised me how people were getting so excited about it. Only later did I realize, it was like explaining the value of a Laser before it existed, and all you knew are light bulbs. Today I truly believe that these systems will revolutionize our space.”
