Sbir phase II: computational fluid dynamics software for quantum computers

Qubitsolve Inc. received a $1.197 million Small Business Innovation Research (SBIR) Phase II award from the National Science Foundation (NSF) Technology, Innovation, and Partnerships program (CFDA 47.084) on September 15, 2025, with a completion date of August 31, 2027. The award funds the development of quantum computing-based computational fluid dynamics (CFD) software designed to overcome computational limitations inherent in classical CFD systems. Building on a Phase I prototype, the Phase II project will enhance software performance and demonstrate its effectiveness through a CFD simulation focused on aircraft noise reduction, establishing a new generation of quantum-enabled CFD technology applicable to complex fluid flow problems previously impossible to solve on conventional computers.

The deliverables from this cooperative agreement will provide industrial-grade CFD software tools for aerospace applications with potential expansion across automotive, chemical, energy, and healthcare sectors. By enabling solution of previously intractable CFD simulations, the technology is expected to reduce development costs and timelines while supporting superior product design in areas such as fuel-efficient aircraft and lower-emission energy systems. The project, performed in Everettville, WV, represents a partnership between academic and industrial researchers intended to advance U.S. competitiveness in quantum computing commercialization and national defense capabilities through enhanced design and certification processes for aircraft, missiles, armored vehicles, and naval systems.

Abstract

The broader impact of this small business innovation research (sbir) phase II project will result from the creation of one of the first industrial applications of quantum computing. This technology will initially be used to address challenges in the aerospace industry. IT may play a crucial role in national defense by aiding in the design of aircraft, missiles, armored vehicles, and naval systems. Over time, the technology will be applicable in other sectors, including automotive, chemicals, energy, and healthcare. This innovative technology will help companies reduce costs and time in developing superior products, such as safer aircraft that consume less fuel, energy plants that emit less carbon dioxide (CO2), and devices that deliver drugs more effectively. The project involves a partnership between academic and industrial researchers. Ultimately, this project will support U.S. Leadership in quantum computing. This sbir phase II project will develop a new computational fluid dynamics (CFD) technology that leverages quantum computers. Engineers use CFD to predict fluid flow and to design or troubleshoot various systems, including airplanes, automobiles, and chemical reactors. However, some CFD simulations are currently impossible to perform on classical computers, even though information from these simulations could save substantial costs ? Potentially hundreds of millions of dollars in certifying aircraft, for example. A quantum CFD algorithm that overcomes the limitations of classical CFD was implemented in a software prototype during the phase i project, and its performance has been evaluated. Phase II aims to significantly enhance the software performance and demonstrate its effectiveness through a CFD simulation focused on aircraft noise reduction. This project will establish a new generation of CFD technology based on quantum computing, enabling the solution of CFD problems that are currently unsolvable. This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the foundation's intellectual merit and broader impacts review criteria.- subawards are planned for this award.
