Quantum information science and engineering is a rapidly growing field that seeks to leverage the intrinsically quantum-mechanical properties of light and matter in attaining superior performance in the acquisition, transmission, manipulation and extraction of information in the contexts of various computing, communications and sensing tasks, compared to corresponding technology incumbents that do not leverage those quantum properties. For example, squeezed light enables higher-precision optical phase measurements whose benefits carry over to use cases in laser gyroscopes, beam deflectometers, radiofrequency photonic sensors, gravitational-wave detection, network resilience and more. Leveraging entangled electronic spins of an array of artificial atoms in diamond could enable higher-precision magnetic field imaging whose use cases span microchip tomography to active neuronal-signal detection. The higher capacity of quantum-powered optical receivers could enhance the range and communications rate of deep-space lasercom links by several fold in the photon starved regime. Quantum-theory-assisted designs of imaging systems could assist in resolving objects or detecting a sudden change in an unresolved scene, using a telescope of a given size, far quicker than a conventional focal plane sensor can. However, quantum enabled technologies are not a panacea. One needs to carefully evaluate the concepts and regimes of operation where quantum techniques could, in principle, afford a meaningful improvement. In this talk, I will give a high-level overview of the field, and provide flavors of use cases of quantum techniques in sensors and imaging systems of potential intelligence, surveillance and reconnaissance relevance, some use cases of quantum enhanced communications and networking, and regimes where seeking quantum-driven improvements in near-term-realizable systems may be the most promising. I will close with an overview of the National Science Foundation (NSF) Engineering Research Center for Quantum Networks, and a discussion of technological readiness, challenges and opportunities.
