In a notable advancement in hybrid quantum-classical computing, Quantum Machines has successfully demonstrated an end-to-end NVIDIA CUDA-Q program operating across live qubits and a classical PPU processor. This was achieved via NVIDIA’s NVQLink, showcasing a novel methodology for developing applications that leverage both quantum and classical computing resources. The initiative merges Quantum Machines’ cutting-edge quantum control technology with NVIDIA’s CUDA-Q platform, which is open-source and designed for quantum-GPU computing, alongside NVQLink for a high-speed interface between quantum controllers and accelerated computing systems.
This integration allows developers to craft quantum applications using widely-used programming languages such as Python, C++, and QUA. Traditionally, creating these applications required manual crafting of low-level control sequences specific to quantum hardware. The demonstration involved executing code written with CUDA-Q through Quantum Machines’ control stack across various processors, including quantum processors, GPUs, and CPUs. With NVIDIA NVQLink, the system facilitates swift communication between quantum and classical computing resources, achieving a complete exchange in roughly one microsecond.
The new technology is being presented at IEEE Quantum Week in Toronto, offering researchers and engineers an opportunity to witness the system in action with live quantum hardware. Yonatan Cohen, CTO of Quantum Machines, expressed enthusiasm about the collaboration with NVIDIA, noting that the union of these technologies empowers quantum developers to accelerate the journey toward large-scale quantum computers.
The integration aims to make quantum processors, or QPUs, function more seamlessly within larger computing systems. By collaborating closely with CPUs and GPUs, QPUs are intended to behave as a unified quantum supercomputing system. As Sam Stanwyck, Director of Quantum Product at NVIDIA, explained, the transformative potential of quantum processors is fully realized when they operate in conjunction with GPUs and CPUs.
Quantum Machines has incorporated NVIDIA NVQLink into its Orchestration Platform to link the hardware responsible for qubit control and measurement with NVIDIA’s accelerated computing capabilities through a low-latency connection. This setup supports real-time processing, allowing quantum operations to be executed on the QPU while classical tasks are handled by CPUs and GPUs. The low-latency connection is critical for tasks requiring rapid quantum-classical interaction, such as quantum error correction. This ongoing development aims to advance more accessible and scalable quantum computing, paving the way for future applications that demand real-time coordination between quantum and classical systems.
