The Hybrid Processing Unit (HPU) is an advanced classical processor central to Quantum Machines’ Hybrid Control approach. By positioning classical computing resources as close as possible to the quantum hardware, the HPU enables real-time execution of quantum control protocols with minimal overhead, ensuring rapid comprehensive and frictionless operation.

Built into every OPX1000 front-end module (LF-FEM and MW-FEM) and OPX+ system, multiple HPUs operate as one, orchestrating control, readout, and calculations, handling data sharing and synchronization.

Unmatched Real-Time Processing Capabilities

The HPU is a 16-core classical processor designed for parallel, real-time quantum control operations. These cores can simultaneously generate and manipulate pulses to control, receive and process data from qubits, and execute real-time Turing-complete classical calculations. The result is ultra-fast feedback loops, enabling real-time adaptive control based directly on measurement outcomes. With the HPU technology at their core, OPX hybrid controllers can execute the most complex dynamic protocols and deliver unmatched performance. They significantly reduce sequence execution times, achieving speeds tens or even hundreds of times faster than other controllers.

  • Active reset latency < 160 ns
  • QPU utilization in Cross-Entropy Benchmarking (XEB) >97%

Unique External Acceleration

The NVIDIA DGX Quantum solution, co-developed with NVIDIA, establishes a direct high-bandwidth, ultra-low latency connection between GPU/CPU resources and the HPU. This ultra-fast data link provides communication speeds that are at least 1,000 times faster than conventional interfaces, enabling powerful external classical computing resources to directly accelerate quantum control tasks. Such integration significantly enhances advanced hybrid workflows critical for scaling quantum systems – including quantum error correction, accelerated calibration protocols, and emerging hybrid quantum – classical algorithms.

  • GPU/CPU – HPU data round trip latency <4 µs

Easy as Pseudo Coding

HPUs are programmed with QUA – an open-source programming language designed specifically to combine quantum control with classical computation and intuitive control flow. QUA provides pulse-level programming while remaining super easy to use and understand as pseudo coding. QUA is central to Quantum Machines’ hybrid development platform which includes a comprehensive library of ready-to-use control applications that significantly reduce development time. As part of this platform, QUA programs can also be seamlessly integrated and controlled through QUAlibrate, Quantum Machines’ automated, scalable calibration solution for quantum computers powered by OPX hybrid controllers.

A&B roadmap enabled by OPX

"Quantum Machines' OPX played a key role in our roadmap. It enabled us to get the best control electronics out there [FPGA] without having to learn how to program them. QM provides a very scalable, very easy to use and very powerful hardware, which allows us to focus on the quantum science."

Théau Peronnin CEO and Co-Founder Alice & Bob

Mid-circuit calibration accelerates advanced teleportation research

“The Quantum Machines OPX control system has been an enabling technology for our research. It provides unparalleled flexibility and ease of use for experiments requiring real-time quantum feedforward control. With the integrated high-resolution time tagging, this platform is a no-brainer for advanced quantum networking experiments.”

Prof. Andrei Faraon William L. Valentine Professor of Applied Physics and Electrical Engineering, Caltech

Significantly streamlining the experimental process

”Diraq is delighted to partner with Quantum Machines, and credits their OPX control system, with its real-time capabilities, as instrumental in achieving the results outlined in our research.  The ease of programming sequences in QUA significantly streamlined the experimental process.”

Prof. Andrew Dzurak CEO, Diraq

Outstanding support. Performing and easy-to-use product

“My group is completely satisfied with the multiple OPX systems we’ve purchased. Qubit bring-up is fast and easy, as is optimization of high-fidelity microwave and z-pulse gates. The technical support team at Quantum Machines is outstanding.”

Prof. Robert F. McDermott University of Wisconsin-Madison

Simple to use, yet very powerful

“We are very impressed to see how simple yet powerful the OPX controller is, as we rebuilt our noise spectrometer for NV centers in a fraction of the time it took us with other instruments. Now, a student with no experimental experience can run the system autonomously, even programming new and advanced dynamical decoupling sequences which include real-time computation. QM's controller is easy to use, and its unique capabilities enable fast and steady progress in our lab.” 

Prof. Chandrasekhar Ramanathan Dartmouth College

Fast development & great support

“Incorporating the OPX+ in our measurement instruments allowed us to set up time-domain measurements in minutes, seriously speeding up our sample characterization process. ​

With the provided extensive live online help we get the support from QM's experts to further debug any problems arising during measurements. With QM support Qilimanjaro can deliver their differential Analog Quantum Computers based on superconducting qubit technology.” ​

Daniel Szombati Senior Hardware Quantum Engineer, Qilimanjaro Quantum Tech​

Using the OPX has been simplifying our work in many respects

"Using the OPX has been simplifying our work in many respects due to the intuitive implementation of sequences within QUA. In addition, the support by QM helped us debugging possible issues with swift responses and an easy and informal way of getting in touch over Discord.”

Most flexible and user-friendly system in our lab

"OPX played a crucial role in our advanced quantum experiments. This platform is the most flexible and user-friendly system in our lab. It saved us a significant amount of time, enabling us to concentrate on quantum science and make progress much faster compared to writing our own code. Furthermore, the Quantum Machines customer success team has been extremely helpful in addressing our needs and maximizing the solution's full potential."

"The QUA python interface is great, everything you want to do is just three intuitive lines of code. The OPX is one of the only things in the lab that is working exactly as it should."

Dr. Josiah Sinclair NSERC Postdoctoral Research Fellow

I have rarely encountered a company as remarkable as Quantum Machines

"I regard Quantum Machines as the quintessential example of how deep-tech companies should operate in harmony. Their OPX+ devices exemplify excellence, and the team's unmatched business ethos sets them apart. From unboxing the OPX+ to the first measurements is a truly exhilarating experience. They consistently go above and beyond for their customers, ensuring mutual success. Transitioning from academia to the startup realm, I have rarely encountered a company as remarkable as Quantum Machines."

Dr. Gopi Balasubramanian CEO and Co-founder XeedQ
