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.11 For example, "superconducting quantum interference devices" are already being used to measure brain activity in hospital-based magnetoencephalography (MEG) scans.
The scope of future applications for quantum technologies include use as very high precision clocks (for GPS satellites among other applications); magnetic sensors (such as miniaturized handheld NMR scanners for medical imaging, geological surveys and nuclear monitoring)12; gravitational detectors (for geological prospecting, mining and autonomous vehicle safety); electromagnetic field sensors (for medical applications, materials development and communication technology), and accelerometers and gyroscopes (for navigation and autonomous transportation).
