Abstract:
The highest resolutions in astronomical imaging are achieved through interferometry, the process of combining wave information from multiple separate telescopes. Interferometry in radio, and more recently in the microwave, have yielded spectacular results; and while optical ultimately holds the most promise, its traditional techniques are hitting technical limits. We will explore how optical interferometry could potentially take great leaps forward with the application of quantum information technologies, starting with basic quantum optics and then further with the use of quantum memories, entanglement distribution, and more. We then describe a project now in development using quantum optics to achieve precision stellar astrometry and discuss its utility for cosmology, dark matter, gravitational waves, and possibly even exoplanets.
