Quantum systems can be exquisite sensors thanks to their sensitivity to external perturbations. This same characteristic also makes them fragile to external noise. Quantum control can tackle the challenge of protecting a quantum sensor from environmental noise. while strongly coupling the sensor with the field to be measured. http://www.spidertattooz.com/PRESTIGE-Crystal-1122-Rivoli-12mm-Crystal-Agave-Ignite-1-Piece/
