Twinleaf LLC

Twinleaf LLC is a woman-owned small business specializing in advanced magnetometer and sensor technologies based in Plainsboro Township, New Jersey. The company leverages quantum and atomic-based sensing solutions to develop innovative instruments for federal research and defense applications. Twinleaf has established itself as a trusted partner for the Department of Defense and related agencies, demonstrating significant technical capability through its participation in the Small Business Innovation Research program and other federal contracting vehicles.

Twinleaf has delivered a diverse portfolio of quantum and atomic-based sensing products and research services across multiple federal agencies. The company's primary contracting vehicle has been DARPA's Small Business Innovation Research program, through which it has received numerous Phase II awards totaling over $9.3 million, including contracts for stable quantum vector magnetometers, accurate and reliable quantum vector magnetometers, magnetic reference sensors for GPS-free navigation, and low-cost laser helium-3 magnetometers. Additionally, Twinleaf has received Phase II SBIR contracts from the Naval Air Warfare Center for advanced magnetometer development valued at approximately $1.95 million and from the Washington Headquarters Service for RF quantum sensors (developed in collaboration with George Mason University) valued at $1.697 million. The company has also performed work under smaller purchase orders from the Office of Naval Research for magnetic shield sets, bipolar current supplies, VMR vector magnetometer systems, and optically pumped gradiometers. An Air Force Research Laboratory Phase I SBIR contract for microfabricated, vacuum-packaged alkali reference cells rounded out its SBIR portfolio. Beyond SBIR programs, Twinleaf received a Cost Plus Fixed Fee contract from DARPA for the Science of Atomic Vapors for New Technologies program valued at over $2 million. All Twinleaf prime contract awards have been designated as Total Small Business set-asides except for the SAVANT program contract and certain Office of Naval Research purchase orders. The company has also served as a subcontractor to Sri International on the MACARONI program, providing support for sensor design and construction, including sensor head and control/readout electronics.

Twinleaf currently holds two Other Transaction indefinite-delivery/indefinite-quantity contracts awarded by DARPA. The Robust Quantum Sensors program, awarded on August 1, 2025, carries a ceiling value of $6.1 million and is designed to transition quantum sensing capabilities to Department of Defense platforms. This contract, which operates without set-aside restrictions, provides DARPA flexibility to fund iterative quantum sensor development and evaluation activities aligned with evolving defense requirements. The second IDIQ, awarded on July 10, 2023, is valued at approximately $993,725 and supports research, development, testing, and evaluation services for a Helium Optical Thermoimmune Magnetometer. This Other Transaction vehicle similarly affords DARPA the flexibility to issue task orders for advanced magnetometer development as the technology matures. Both contracts reflect DARPA's confidence in Twinleaf's capabilities to advance quantum sensing technologies and represent the agency's commitment to supporting the company's transition of innovative sensor systems into operational defense applications.
