Designed for quantum physics, the QDAC series of products are high-precision low-noise computer-controlled voltage generators for DC and intermediate-frequency control of quantum electronics and quantum computer qubits. In addition to their precise and stable voltage output, QDACs can measure output currents – for example, to detect leaking gates or shorted bonding wires. QDACs have 24-channels and thus offer a cost-effective way to gain many high-quality D/A converter channels.
QDAC is a high-precision, 25-bit resolution, ultra-low-noise computer-controlled DAC with 24 voltage channel generators operating at a sample rate of 1MS/s. It is designed for DC and intermediate-frequency control of quantum devices, including, for example, gate electrodes and flux bias coils in qubits. It is also a very versatile instrument that can be used for many other purposes.
Performs fast multi-dimensional gate voltage sweeps with a 1 MS/s output rate.
Multiple OPX+ and QDAC units can be stacked and synchronized to operate as one advanced quantum control system for an QPU size DC to 400 MHz.
“QCage integrates seamlessly into our workflow of preparing and loading QPUs and supports higher throughput in our lab. Our research directly benefits from QCage's innovative design and engineering.”
“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.”
“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.”
