Quantum Gravimeter

Quantum Gravimeter

The quantum gravimeter, the first commercial device of its kind in the UK, uses quantum interference of matter waves to measure the local value of gravitational acceleration, or ā€˜gā€™, with very high precision. Objects with different mass cause small fluctuations in the value of g measured on the surface of the Earth. The quantum gravimeter can be used to sense these objects hidden under the surface in a non-intrusive manner.
