Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with NVIDIA, has demonstrated the world’s largest full quantum chip simulation using 6,724 NVIDIA GPUs on the Perlmutter supercomputer. The announcement, made on November 19, 2025, highlights the use of GPU-accelerated Electronic Design Automation (EDA) tools for quantum chip design. The simulation modeled a 1 cm quantum chip with over 10 billion grid points at micron resolution, capturing critical details such as cross-talk and signal distortion. Key highlights include:

Utilizing NVIDIA's CUDA platform to accelerate the ARTEMIS simulation package.
Modeling a full quantum chip on NVIDIA GPUs within the Perlmutter supercomputer.
Demonstrating the ability to observe the propagation of control signals through the chip at femtosecond time resolution.

The ARTEMIS platform optimizes simulations for parallelization on NVIDIA GPUs, providing a full-wave, time-domain electromagnetic solver. This allows for accurate modeling of large, chip-scale systems while preserving fine spatial and temporal details. The simulation, which took nearly eight hours on the full system, modeled 1.5 million time steps to reach 1 nanosecond of physical time. By using the NVIDIA CUDA platform, researchers can test novel qubit architectures, reduce noise sources and cross-talk, and validate quantum chip designs before fabrication. The NVIDIA CUDA-Q platform offers tools to accelerate quantum computing workloads. This includes projects such as Google’s Willow chip. This simulation demonstrates a crucial step toward building more robust quantum chips and accelerating the development of quantum computing technologies.
