Quantum-Classical Integration and Control Highlights
A modular portfolio for all your control, filtering, and sample holder needs
Quantum Machines’ solutions are based on a wide portfolio, which includes room-temperature controllers and cryogenics electronics implementing novel technology.
The OPX1000 offers a unique control paradigm thanks to the combination of its Pulse Processing Unit (PPU), for classical computation during quantum sequences, and its cutting-edge analog frontend, with direct digital synthesis drive and excellent readout capabilities.
The QDAC-II and QDAC-II-compact offer high-density ultra-stable DC and low-frequency controls and, with QSwitch and QBox, allow for flexibility in DC controls at any scale, without trading off on low noise levels.
The cryogenics filters and sample holders from Quantum Machines offer reliable and tested ways to support your samples and signals in cryogenic environments without limiting coherence and sample integrity.
A software suite with pulse-level programming, automated calibrations, and high-level integration
Quantum Machines’ Orchestration Platform allows users to easily program quantum systems of any scale from various levels of the programming stack, by means of multiple layers of abstraction and compilation.
QUA, QM’s open-source pulse-level programming language, enables writing hybrid control sequences, intuitively and from a Python environment. QUA is the core of QM’s software ecosystem, seamlessly combines classical and quantum programming in a comprehensive, expressive, and scalable open-source language. Use the same programming model from one qubit to thousands.
Then QUAM, the qubit abstraction software, and QUAlibrate, the automated calibration framework, enable fully automated calibration workflows which run simultaneously on any number of qubits. Download the QUA Libraries and build on years of accumulated quantum-control expertise to get started faster.
Scalable and Automated Qubit Calibration Framework for High-Fidelity Quantum Systems
QUAlibrate transforms quantum calibration into a fast, automated, and scalable process. Through a graph-based architecture it enables fast and fully parallelized multi-qubit tune-up increasing fidelity and reducing downtime.
Calibration workflows are defined as customizable graphs of QUA-based nodes, allowing full code-level control over execution and logic. Graphs include Pulse Processing Units (PPU) compute and sequences via QUA, but also classical acceleration via the Open Acceleration Stack. Advanced graph logic optimizes calibration efficiency and allows for complex bring-up and retuning routines to be completely automated.
Powered by QUA and QUAM, QUAlibrate abstracts hardware details, ensuring consistency and scalability across systems while accelerating development and maintaining high-fidelity performance.
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.

Thanks to the super-fast on-board data processing of the OPX we could resolve the nonlinear phenomena of our superconducting quantum circuits. With conventional AWGs and electronics this would have taken an impractical long time. The OPX is extremely easy to operate and substantially changes the paradigm of data acquisition and analysis procedures in quantum labs.

I must say I'm very happy with QM's Quantum Orchestration Platform. It's the single most reliable piece of equipment I've got in the lab. I operate it remotely and never had any problems. I strongly recommend the OPX and the QOP to my colleagues. It is by far the simplest way to do qubit physics.

Using high-fidelity rapid readout and real-time state assignment, we were able to do an active reset and generate this noiseless plot (100,000 times averaging) in 20 seconds. Without active reset (assuming 400us between sequences) it would have taken roughly an hour to get a similar quality plot.” Dr. Eunjong Kim Painter Lab, Institute for Quantum Information and Matter (IQIM), Caltech Simultaneous control and reset at scale – 10-qubit device example X180

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.

FAQs
How is qubit readout performed across different qubit modalities?
Readout depends on the modality, and QM’s hardware handles each in real time: superconducting and spin qubits are read out by digitizing the microwave or RF signal from a coupled resonator, while atoms, ions, and defect centers are read out optically using built-in photon counters and time taggers, with camera-based imaging for atom arrays. In every case the OPX captures the raw signal, classifies the qubit state, and can feed that result straight back into the running program. Keeping readout and classification on the controller, rather than shipping data to a separate computer is what makes low-latency, mid-circuit measurement possible.
What is the difference between a physical and a logical qubit, and how does the control system enable logical qubits?
A physical qubit is a single real device, while a logical qubit is an error-corrected qubit built from many physical qubits, so errors can be detected and corrected as a computation runs. Quantum error correction depends on a tight real-time loop: measure many qubits mid-circuit, decode which errors occurred, and apply corrections, all within the qubits’ coherence window. This is exactly where the control system matters: it must perform measurement, classical decoding, and feedback fast enough to keep up, which is why QM’s architecture brings classical processing as close as possible to the qubits to eliminate the latencies that error correction is so sensitive to.
How do you program and calibrate qubits with Quantum Machines?
Qubits are programmed on QM hardware using QUA, a pulse-level language that lets developers implement quantum sequences and classical processing around them in a single program. Routine bring-up is handled by QUAlibrate, QM’s automated calibration framework, so labs spend less time manually tuning and more time running experiments. And because sequences run directly on the controller, deep protocols like randomized benchmarking execute in minutes, with no uploading or compilation time.
What hardware is used to control qubits?
Qubits are controlled by specialized quantum control hardware that generates the microwave, RF, and laser-driving pulses, captures readout signals, and runs real-time classical processing to steer the experiment. Quantum Machines’ OPX controllers, for example, integrate control and real-time processing in a single platform and bring classical resources as close as possible to the qubits, across superconducting, spin, and atom-based modalities. This proximity enables ultra-fast feedback,including active resets as fast as 120 ns, that is essential for adaptive protocols and error correction.
