The U.S. Department of Energy has awarded MagiQ Technologies a contract to develop quantum sensors for energy and minerals exploration. MagiQ’s CTO, Dr. Caleb Christensen, explains why pushing sensing below the limits of classical physics matters for the resources the world depends on.
The challenge in exploration has always been the same: you can’t characterize what you can’t measure. The reservoirs and mineral deposits that matter most sit miles underground, in complex geology, under high pressure, and sometimes high heat. The decisions made about them are only as good as the data coming back from the field, and conventional sensors are running out of room.
Photonic sensing already changes that. By using light instead of electronics, fiber-optic sensors survive the heat and pressure of deep wells and capture the full multi-component wavefield that interpretation now needs. This DoE contract takes the next step, from photonic measurement to genuinely quantum measurement.
The physics behind it is simple enough. Every classical sensor is ultimately limited by noise that comes from the quantum nature of light itself, the standard quantum limit. Non-classical states of light push that floor lower, so a sensor can pick up signals that would otherwise be lost in the noise. In the field, that means catching fainter signals from deeper down, and trusting what comes back.
Energy and minerals exploration are a natural place to start. Geothermal reservoirs, carbon storage sites, and critical-mineral deposits share one problem: the value sits in the subsurface, and the environment is hostile to whatever you send down to observe it. Sensors that work at the quantum level give operators a clearer, continuous picture of what is actually happening underground.
There is a bigger reason the Department of Energy is backing this. As the country invests in energy security and a more resilient critical-minerals supply chain, seeing the subsurface accurately stops being a convenience and starts being infrastructure. MagiQ has spent more than two decades turning quantum and photonic physics into systems that work in the field, and this contract carries that work into a new generation of sensing for the resources everything else runs on.
