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.

GPU-Powered Hybrid Control

OPX1000 redefines hybrid quantum-classical computing with seamless GPU acceleration, delivering data transfer speeds over 1,000 times faster than other controllers. Through NVIDIA DGX Quantum, it establishes an ultra-fast link between the HPU and GPUs/CPUs, enabling tightly synchronized hybrid algorithms that push the boundaries of large-scale quantum computing. By eliminating bottlenecks between quantum control and classical processing, OPX1000 unlocks real-time quantum error correction, accelerated calibration, and next-generation hybrid algorithms – all with minimal latency and maximum efficiency.
