California Governor Gavin Newsom signed legislation on September 30, 2026, establishing a strategic framework for fusion energy development and announcing a new funding commitment for quantum technologies. The signing ceremony took place at a quantum laboratory at the University of California, Berkeley. Alongside the legislative action, Newsom unveiled a $30 million investment designated for quantum and deep-space research initiatives.
What it means
The signed measures create a strategic plan for fusion energy in California, expand opportunities for related research and development, and outline a commercial strategy for the sector. The legislation also advances the development of fusion manufacturing capabilities within the state. These actions align with the California Jobs First Economic Blueprint, which identifies quantum and fusion as priority sectors.
Assemblymember Lisa Calderon (D-Whittier) authored AB 2647, which directs an assessment on new nuclear power plants to support the state’s goal of achieving 100% zero-carbon electricity by 2045. Senator Jerry McNerney (D-Pleasanton) authored SB 925, which establishes the fusion energy strategic plan. The investment aims to leverage public-private partnerships and cultivate a quantum start-up ecosystem, building on landmark legislation signed in 2025 that launched the Quantum California initiative.
