What Rydberg Technologies does
Rydberg Technologies Inc. is a privately held quantum technology company founded in 2015 and headquartered in Ann Arbor, Michigan. The company develops and manufactures atomic quantum devices based on Rydberg atom technology, where highly excited atoms with a single quasi-free electron are used to receive electromagnetic signals over a frequency range from DC to THz with high precision. Its flagship product, the Rydberg Field Measurement System (RFMS), is described as the world's first atomic RF sensor, providing absolute SI-traceable measurements of RF electric fields from near-DC to millimeter-wave with 0.1% measurement precision, representing an improvement of more than 10x over classical antenna standards. The company also produces atomic vapor cells, reference devices, and (through its Berlin-based subsidiary Rydberg Photonics GmbH) hybrid-integrated laser systems and optical frequency references that serve as building blocks for quantum technology applications.
The company's business model centers on direct enterprise sales of quantum hardware and devices (RFMS, atomic vapor cells, photonic engines, lasers) supplemented by revenue from government contract awards with agencies including DARPA, NIST, DIU, NSF, and NSIC. Rydberg Technologies serves two primary customer segments: defense and government (vertical priority) for RF sensing, signal reception, metrology, antenna testing, and atomic standards; and commercial/industrial quantum for compact deployable atomic quantum devices. A secondary research and academia segment supplies advanced quantum photonic systems to research institutions. Pricing is not publicly disclosed; engagement is via direct inquiry through the company website contact form or phone. The company maintains a 1-10 person specialized team and distributes through direct enterprise sales in North America and via its Berlin-based Rydberg Photonics GmbH subsidiary in Europe.
Rydberg Technologies is founder-led, with Dave Anderson serving as CEO and co-founder of both the parent company and the Rydberg Photonics GmbH subsidiary. The company has received approximately $2.5 million in cumulative disclosed funding from the National Science Foundation (2017, 2020) and National Security Innovation Capital (2021), with additional revenue presumed from ongoing government contract awards. In October 2025, the company launched Rydberg Photonics GmbH, a Berlin-based spin-off from Germany's Ferdinand-Braun-Institut, marking its first material geographic expansion and broadening its product portfolio into photonic systems for quantum sensors, clocks, and communications.
