  Microarcsecond resolutions afforded by an optical-NIR array with
kilometer-baselines would enable breakthrough science. However significant
technology barriers exist in transporting weakly coherent photon states over
these distances: primarily photon loss and phase errors. Quantum telescopy,
using entangled states to link spatially separated apertures, offers a possible
solution to the loss of photons. We report on an initiative launched by NSF
NOIRLab in collaboration with the Center for Quantum Networks and Arizona
Quantum Initiative at the University of Arizona, Tucson, to explore these
concepts further. A brief description of the quantum concepts and a possible
technology roadmap towards a quantum-enhanced very long baseline optical-NIR
interferometric array is presented. An on-sky demonstration of measuring
spatial coherence of photons with apertures linked through the simplest
Gottesman protocol over short baselines and with limited phase fluctuations is
envisaged as the first step.
