The bright star in the center, Fomalhaut, is surrounded by an ancient debris disk of uneven brightness. The disk is closer to the star in the south, where the disk is wider and fainter, and further from the star in the north, where the disk is narrower and brighter. The dotted ring shows the possible orbit of a planet implied by Lovell et al. Credit: NSF/AUI/NSF NRAO/B. Saxton

Pictorial representation of how QELM on classical data works. Classical data are encoded in a physical system from which we collect a set of measurements. The outcomes undergo a linear post-processing which maps the outcomes of the reservoir to the output of task. -- astro-ph.IM
