Abstract
M agnetic induction tomography is a contactless, noninvasive method for mapping the electrical and magnetic properties of a material. The technique is used in geophysical surveys and in the nondestructive testing of metallic objects, and it could have various uses in medical imaging, such as for monitoring brain activity. Now Eugene Polzik and his colleagues at the University of Copenhagen in Denmark show that quantum phenomena can increase the sensitivity of magnetic induction tomography [1]. The team’s demonstration is the latest example of quantum-enhanced sensing, which has previously been illustrated in the detection of gravitational waves, for example.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
