Quantum sensing, quantum communication and quantum computing have permeated industry and academia with a flurry of quantum strategies developed to advance quantum technology to real-world applications in the geosciences. An overarching issue that still looms is whether advantages of quantum principles are translating into tangible advances? Quantum sensors have demonstrated their advantages, compared to current sensors, in sensitivity, sampling rate and resolution. These improvements are based on laboratory experiments, however, those advances often do not directly translate into improved applications. The uncertainties related to the complexity of the Earth and its measurement environment often overshadow sensor improvements. This talk will discuss examples of quantum sensing, implementation approaches, and a general overview of what sensors are available today and how they could advance geoscience research and applications or not.
