Trusted by Builders of the Largest and Most Advanced Quantum Computers in the World

OPX1000 is a state-of-the-art controller designed for large-scale quantum computers. This modular solution features an unmatched density of channels and is easily expandable to cost-efficiently control even the largest quantum processors available. Scale up your quantum computer while enhancing flexibility and performance with OPX1000.

Industry’s Highest Channel-Density and Seamless Scalability

With its modular design OPX1000 features up to 64 output and 16 input analog channels packed into a 3 rack units (U) chassis, the highest in-class density of control and readout channels. Moreover, multiple OPX1000 units can be connected to seamlessly support any QPU size. This exceptional channel density and scalability facilitate cost-effective control over today’s largest Quantum Processing Units (QPUs) as well as those planned for the future.

Unmatched Processing PowerTM

With up to 10 high-end FPGAs, OPX1000 offers the highest level of classical processing resources available in any dedicated quantum control solution. This enables robust computation during quantum sequences, which is critical for advanced quantum algorithms such as VQAs, error mitigation, error correction, and other complex decoding schemes. Additionally, the combination of this processing power with continuous firmware (logic) updates allows for limitless possibilities of future enhancements, including features and capabilities that operate within quantum coherence timescale – all without the need to modify or replace the hardware.

Easy to Use

OPX1000 is programmed using QM’s extremely intuitive pulse-level language,  QUA, allowing researchers and developers to program complex quantum algorithms with ease. QUA seamlessly code, just like writing pseudo-code, programs ranging from the simplest Ramsey on a single qubit to a complex multi-qubit circuit involving real-time Hamiltonian estimation, feedback and even multiple OPX1000 controllers. For example, 2-qubit randomized benchmarking with sequences selected while running and gate depth of 10,000 is easily programmed in a few lines of code. QUA programs are executed by OPX1000 PPUs in real time, delivering the industry’s best real-time capabilities and fastest runtimes.

State-of-the-Art Analog Frontend

Optimized for the needs of quantum computers at scale, OPX100 features a state-of-the-art analog frontend with jitter < 0.3 ps, up to 750 MHz bandwidth, 2 GSPS, amplified mode of 5 Vpp with a fast clean step response < 850 ps, low 1/f noise and more.

Ready for HPC Environments

OPX1000 is fully compatible with DGX-Quantum – a co-developed solution by Quantum Machines and NVIDIA for hardware quantum acceleration, with amazingly fast GPU-OPX1000 interface of less than 20 microseconds delay. This enables using Grace Hopper GPU resources to execute quantum workflows at scale, such as mid-circuit calibration and QEC. It further facilitates the development of innovative hybrid classical-quantum applications using gate-level programming: OpenQASM3 and NVIDIA CUDA Quantum, while benefiting from deep access to quantum control pulse-level using QUA, allowing for software optimization.
