After a selection through competitive peer review under the DOE Funding Opportunity Announcement for Quantum Information Science Research for Fusion Energy Sciences and a companion National Laboratory Announcement, Rigetti Computing, a Berkeley-based quantum computing company, was awarded a three-year contract to develop a quantum simulation for fusion energy.
The $3.1 million awards from the U.S. Department of Energy comes through as part of an initiative sponsored by the Office of Fusion Energy Sciences (FES) and will be a collaboration between Rigetti Computing, Lawrence Livermore National Laboratory, and the University of Southern California to understand plasma physics, the science underpinning fusion energy. The project also seeks to identify the ability of quantum computers to outperform classical computers in plasma simulation.
The goal of fusion energy research is to use the same principle as the sun to produce a commercially viable fusion reactor that can be an alternative clean and affordable energy source. If a sustainable energy source from fusion plasmas becomes a reality, it could create important economic, environmental, and national security benefits.
The collaboration will make use of quantum computing to explore and advance the fields of fusion energy and quantum information science. The project will produce the first exploration of carefully engineered multi-qubit gates and interactions for simulating plasma dynamics on a quantum computer. It will also develop and apply control pulse engineering and dynamic error suppression techniques that are expected to enable long-duration simulations with high effective gate depth.
The project will leverage and extend QUIL and associated programming libraries, such as Quil-T. Quil is a quantum instruction language (from which we derive the name Quil-T) that was originally developed by Rigetti Computing to program their cloud-based quantum computer. As an extension, Quil-T is time-domain pulse programming for hybrid quantum-classical computing. The language and its associated compiler are open source and will be made available for anyone to use for any purpose, including the exploration of quantum applications in fusion energy.
