Coherent Control of High-Q Devices
Research into understanding and controlling microscopic quantum mechanical phenomena has led to revolutionary new quantum devices, including quantum sensors and actuators that have unprecedented levels of sensitivity, efficiency, and functionality for a wide variety of tasks. A particularly compelling example is high quality factor (high-Q) superconducting resonators for magnetic resonance. These new devices will be substantially more sensitive than current devices in widespread use. They offer the potential of producing higher resolution medical images, enhancing biological and chemical sensors, and improving materials characterization measurements. Their routine use requires the development of control sequences tailored to the unique properties of these devices. We will apply quantum control theory techniques to develop and demonstrate robust control sequences for these devices, enabling them to have immediate impact in common commercial applications.
