Research Topic Description, including Problem Statement:
Quantum sensors (e.g. atomic magnetometers, NV centers in diamond, atom interferometers, atomic clocks, Rydberg atom electric field sensors) and novel optical sensors (e.g. optical frequency combs, fiber sensors) can show great sensitivity in the laboratory and in some cases have been demonstrated outside of a laboratory environment. However, barriers to more widespread use include the complexity of operating many of these sensors and the instability of the sensors in a relatively uncontrolled environment. For example, some quantum magnetometers require the ambient magnetic field and any field gradients to be carefully tuned, and some sensors with thermal sensitivities require some feed-forward process to correct for temperature fluctuations. The process of nulling ambient fields or measuring thermal response characteristics can be time-consuming and frustrating, because often the sensor systems have complex and nonlinear behaviors that cannot be modeled well. Fortunately, algorithms used in machine learning are often highly suitable for problems such as these. While machine learning is more typically used to analyze data that has already been acquired, this topic is about using these algorithms to improve the performance of the sensor itself. A working quantum or novel optical sensor should be used to quantitatively improve a sensor when using machine learning algorithms as part of the sensor system, where improvement is along performance parameters such as accuracy, speed, robustness to noise and environmental fluctuations, or along system parameters such as size or complexity.
Example Approaches:
To date only a few published examples of machine learning algorithms applied to quantum systems or traditional sensors exist. Some examples include using artificial neural networks along with co-sensor data to increase the accuracy of the thermal calibration of a sensor, using a sequential Monte Carlo algorithm to optimize the Ramsey pulses driving an NV center in diamond in the presence of environmental noise, using Bayesian optimization to find efficient procedures for generating a Bose-Einstein condensate (BEC), and using a conditional variable auto-encoder to decrease the measurement time of a current map of a quantum dot device. Because this is a relatively new approach to improving sensor performance, this topic is not at all limited to the sensors and algorithms described in this topic or in the literature. However, this topic does not include using machine learning algorithms to process data already acquired by a sensor, or to devise new algorithms without testing them on a real sensor, or modeling sensor performance without demonstrating the algorithms on a real sensor.
Relevance to the Intelligence Community:
The Intelligence Community (IC) is always looking for better techniques to perform technical collection. Small, high-performance sensors would allow operation in previously impossible scenarios and with new functionality. They are also more realistically multiplexed which further increases sensitivity and often adds new capabilities such as directionality. Applying machine learning to these sensors can make them much more accurate and robust, making them even more applicable to IC problems.
