Company History

Quantum Signal (QS) is a Limited Liability Company specializing in math-based engineering and custom product development. Headquartered in Saline, Michigan—just south of Ann Arbor, home of the University of Michigan—QS was launched in January 2000 by its co-founders, Dr. William J. Williams and Dr. Mitchell M. Rohde.

The company received a contract from a major automotive OEM in April 2000, and in October of that year moved to its first headquarters in the historical Northern Brewery in Ann Arbor. QS also exclusively licensed two key patents of Dr. Williams' technology from the University of Michigan in early 2001.

Over the next several years QS continued to attract interest and increased work from an expanding clientele. QS engineers applied their highly versatile technology to solve a wide range of problems, including enhanced automotive crash analysis, solve noise and vibration issues, enhance defense communications, and perform face recognition. In addition to providing consulting, education, and contract R&D, QS continued to develop in-house technologies for future commercialization.

This in-house technology research lead to a three-year, $1.83M grant from the National Institute of Standards and Technology (NIST) Advanced Technology Program (ATP) in October 2002. The focus of that work was on developing and extending the company's unique, patented pattern recognition technology for biometrics applications. Novel, advanced face and speech-based biometric algorithms were developed under this grant, and some of the technology from this program is in use today in police stations, retail stores, and laboratories around the world.

In November 2002 QS expanded to triple its space and staff, and was recognized a month later for its contributions in Advanced Manufacturing by the Michigan Economic Development Corporation (MEDC – link In 2004 QS formed a new modeling and simulation (M&S) group to bring video gaming technology to more “serious” training and engineering applications. Headquarters were moved again in January 2005 to a larger suite in south Ann Arbor to allow for additional expansion, and in 2005 QS launched an effort to develop advanced ground robotics solutions and make them more intelligent and easy to use. Both the M&S and robotics efforts have grown and flourished since their inception, completing over a dozen major efforts and delivered state-of-the-art products to many customers.

In 2010, QS moved into its current headquarters at historic Union School in Saline, and was named to Crains Detroit's 25 Companies to Watch. In 2013 QS was featured by the Detroit News for its innovative culture and environment. In 2014 QS made history when it was awarded the first autonomous vehicle testing license plates in the State of Michigan.

QS' success story continues in 2015 and beyond, one product at a time!
