Researchers have managed to locate a tunnel under a meter of earth. Using a quantum gravity gradiometer. A technology that shows itself, for the first time, capable of leaving the laboratory and coming into contact with the realities on the ground.
A quantum gravity gradiometer. Funny term. For a funny machine. A gradiometer is a device intended to measure in space, the The gradient in mathematics, a vector

But today, (United Kingdom) announce that they have managed to attenuate these different noises and have found a quantum gravity gradiometer practice. With its help, they detected a tunnel buried one meter below the surface by measuring .
A number of applications in various fields
The researchers estimate that their quantum gravity gradiometer will in the future make surveys cheaper and ten times faster than with conventional sensors. All with increased accuracy and reliability.
The applications envisaged are numerous. Defense and security applications, for example. Since such microgravity measurements could make it possible to reveal the undetectable and thus, to move serenely, including in difficult environments.
The quantum gravity gradiometer could also revolutionize the way we design, build and maintain our homes and infrastructure. It could help identify natural resources — or built structures hidden underground — or even improve the prediction of phenomena such as.
