Quantum Sensing and Imaging
Published in The Quantum World.
Quantum-enabled measuring and calibration devices are already in advanced stages of development. There are sensors, for example, that use quantum properties to achieve higher spatial resolution and larger bandwidth than conventional tools, and their simultaneous sensing of multiple signals enable new functionalities. For example, “superconducting quantum interference devices” are already being used to measure brain activity in hospital-based magnetoencephalography (MEG) scans.
