Supercharging senses
Perhaps one of quantum tech’s most important advantages is its capacity to work at a distance, sensing tiny movements and changes in environmental conditions remotely yet accurately. From charged particles to circuits, an array of quantum sensors are in the works, primarily for detecting magnetic and electric fields as well as measuring parameters like temperature and acceleration.
The problem is, their high sensitivity is also their Achilles’ heel. Many external factors can get in the way of remote sensing, and most quantum sensors are not currently robust enough to filter out the unwanted signals they might pick up. To push the frontiers of this field, researchers strive to extend the range of detection while minimizing noise in the data generated by these systems.
In more controlled setups, quantum sensors are already being used in nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) scans. Most prominently, these instruments enable monitoring of the brain’s activity in noninvasive ways, allowing for a safer and more pleasant patient experience without compromising accuracy.
