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.

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.

The OPX+ and Octave are a dramatic improvement over the traditional homemade AWG plus DAQ systems. These QM instruments offer ease of use across several levels of abstraction: from implementing and optimizing individual pulses to realizing complex experiments with real time processing and feedback. Coding is user-friendly, which makes transmitting the know-how between group members much more straightforward.

Unmatched Real-Time Processing
With up to 8 high-performance PPU (one per front-end module), the OPX1000 hybrid controller has the highest level of real-time classical processing resources available in any quantum controller. This enables robust computation during quantum sequences, which are critical for advanced dynamic algorithms such as VQAs, quantum error correction, fast calibration, and more.
Smooth Scalability
1,000 qubits at beyond! Push the limits of scale with QSync synchronization technology and any-to-any data sharing, ensuring seamless expansion as your quantum processor grows. Multiple OPX1000 units connect effortlessly, sharing measurements and computed results far beyond simple Boolean decisions to maintain precision at any scale. All connected OPX1000 units are programmed and operate as a single unified system, eliminating manual coordination and ensuring smooth, automatic synchronization. Just scale up – no complex software redesign.
Hybrid Programming
OPX1000 is programmed from a hybrid development platform, unifying quantum control, classical computation, and real-time adaptability. At its core, QUA – an open-source, pulse-level programming language – enables effortless quantum-classical programming with a pseudocode-like syntax, supporting real-time decision-making, adaptive feedback, and dynamic control flow. Unlike traditional approaches, control and readout pulses in QUA are generated and adjusted in real time, allowing for on-the-fly waveform manipulation and dynamic protocol execution. A comprehensive library of pre-built control applications further accelerates development and deployment. Seamlessly integrated within this ecosystem, QUAlibrate automates multi-qubit calibration and continuous optimization, ensuring peak performance across quantum processors.
