Delivering Real-time Situational Awareness with Seismic-Acoustic Technology.
Committed to advancing persistent security and surveillance through geophysical performance.

Quantum Technology Sciences designs, manufactures and sells geophysical technology that delivers real-time tactical monitoring along borders and around critical infrastructure assets for the purposes of physical security.

The company has nearly three decades as a U.S. Federal Contractor supplying geophysical expertise to the Department of Defense, Department of Homeland Security, Department of Energy, and other agencies.

The company’s products deliver situational awareness with a three dimensional, 360º detection sensitivity in earth, water, and air. The technology provides automatic detection, classification, and location of a broad range of items of interest to include Pedestrians, Vehicles, Gunshots, Bullets, Digging, Boats, and Planes. Quantum has grown to become a recognized leading innovator in seismic acoustic detection and ranging cross-border tunneling detection technology.

Quantum Technology Sciences is a wholly owned subsidiary of Geospace Technologies Corporation (NASDAQ: GEOS).

For more than four decades Geospace has set the standard for engineering and manufacturing incredibly robust, hardened geophysical data acquisition systems that perform in the world’s most austere environments. Their Oil and Gas customers require systems operate in environments ranging from a mile underwater to remote deserts.

Together, we are the OEM of the 

complete Seismic-Acoustic system spectrum,

from sensor to actionable information.
