QDAC-II is a high-precision, 25-bit resolution, ultra-low-noise DAC with 24 voltage channel generators with a 1 MS/s sample rate and a step size of 0.12 μ. Each of the 24 channels has five voltage generators working in parallel: One for DC, a sine generator, a triangle generator, a square wave generator, and an arbitrary waveform generator.
Performs fast multi-dimensional gate voltage sweeps using a 300 kHz output filter. Once at your operation point, QDAC-II is switchable to an ultra-low noise DC voltage with a 10 Hz output filter and 25-bit resolution, with minimal transients.
QDAC-II offers a high-performance and versatile solution with an endless number of applications. Multiple OPX+ and QDAC units can be stacked and synchronized to operate as one advanced quantum control system.
“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.”
“We were extremely surprised by the flexibility that OPX offers and by how much easier it makes our experiments. Moreover, OPX provides extreme speed-ups. No more frustration due to long waiting times for unwanted results!”
”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.”
“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 >>
“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.”
“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.”
“We are very pleased with the Quantum Orchestration Platform (QOP) control solution. It’s remarkably easy to use, reliable, and flexible, supporting our advanced quantum research needs. The QOP dramatically expedites our research. The Quantum Machines customer success team has been instrumental in addressing all our needs to help us to maximize the full potential of the solution. We already use two systems and strongly recommend it.”
“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.”
“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.”
“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.”
