Researchers Report Field Success with Quantum Gravity Gradiometer

Facebook X LinkedIn Email
BIRMINGHAM, England, March 7, 2022 — Researchers from the UK National Quantum Technology Hub in Sensors and Timing at the University of Birmingham used quantum technology to detect an object hidden below the ground. They said this is the first time a quantum gravity gradiometer has seen practical use outside of laboratory conditions. The gradiometer was developed under a contract for the Ministry of Defence and in the UK Research and Innovation (UKRI)-funded Gravity Pioneer project. The researchers used the device to find a tunnel in real-world conditions, buried outdoors 1 m below the ground surface. The quantum...Read full article

    quantum
    The term quantum refers to the fundamental unit or discrete amount of a physical quantity involved in interactions at the atomic and subatomic scales. It originates from quantum theory, a branch of physics that emerged in the early 20th century to explain phenomena observed on very small scales, where classical physics fails to provide accurate explanations. In the context of quantum theory, several key concepts are associated with the term quantum: Quantum mechanics: This is the branch of...
