NVIDIA Announces New System for Accelerated Quantum-Classical Computing


NVIDIA announced at GTC 2023 spring a new system built with Quantum Machines that provides a revolutionary new architecture. It is specifically engineered for researchers working in high-performance and low-latency quantum-classical computing.

The NVIDIA DGX Quantum brings together the world’s most powerful accelerated computing platform. As a result, it is now the world’s first GPU-accelerated quantum computing system. It is enabled by the NVIDIA Grace Hopper Superchip and the CUDA Quantum open-source programming model. It is also powered by the world’s most advanced quantum control platform, OPX by Quantum Machines.

The combination allows researchers to build extraordinarily powerful applications that combine quantum computing with state-of-the-art classical computing. This, in turn, enables calibration, control, quantum error correction and hybrid algorithms.

“Quantum-accelerated supercomputing has the potential to reshape science and industry with capabilities that can serve humanity in enormous ways,” said Tim Costa, Director of HPC and Quantum at NVIDIA. “NVIDIA DGX Quantum will enable researchers to push the boundaries of quantum-classical computing.”

At its heart, DGX Quantum features a NVIDIA Grace Hopper system connected by PCIe to Quantum Machines OPX+. This enables sub-microsecond latency between GPUs and quantum processing units (QPUs).

“We are heading toward a new age of quantum computing that is more accessible to more researchers than ever,” said Itamar Sivan, Co-Founder of and CEO at Quantum Machines. “Our collaboration with NVIDIA on the DGX Quantum system will enable a new generation of innovators to solve some of the world’s greatest challenges.”

Grace Hopper, which integrates the high-performance NVIDIA Hopper architecture GPU with the company’s new Grace CPU,  is supercharged for giant-scale AI and HPC applications. It delivers up to 10x higher performance for applications running terabytes of data. It then gives quantum-classical researchers unprecedented power to solve the world’s most-complex problems.

OPX+ is a universal quantum control system that brings real-time classical compute engines into the heart of the quantum control stack. This maximises the performance of any QPU and opens new possibilities in quantum algorithms. Both the Grace Hopper and OPX+ systems can be scaled to fit the size of the system, from a few-qubit QPU to a quantum-accelerated supercomputer.

DGX Quantum also equips developers with NVIDIA CUDA Quantum, a powerful unified software stack now available in open source. CUDA Quantum is a hybrid quantum-classical computing platform that enables integration and programming of QPUs, GPUs and CPUs in one system.

NVIDIA announced a new group of partners integrating CUDA Quantum into their platforms, including quantum hardware companies. Some of them are Anyon Systems, Atom Computing, IonQ, ORCA Computing, Oxford Quantum Circuits and QuEra. Other partners are quantum software companies such as Agnostiq and QMware. NVIDIA has also partnered with supercomputing centres National Institute of Advanced Industrial Science and Technology, IT Center for Science (CSC) and National Center for Supercomputing Applications (NCSA).
