1. A method comprising: receiving a plurality of photon beams at a sensor system, wherein the plurality of photon beams are from a far-field scene; wherein a first aperture receives a first photon beam in the plurality of photon beams and a second aperture receives a second photon beam in the plurality of photon beams; wherein the first aperture is physically separated from the second aperture; interfering each of the first photon beam and the second photon beam in the plurality of photon beams with a corresponding source photon beam in a plurality of source photon beams generated by a coherent source to form a plurality of interference beams, wherein each of the plurality of source photon beams has a non-classical state in which fluctuations in a photon-number of the each of the plurality of source photon beams is reduced to within selected tolerances; and forming an output signal based on the plurality of interference beams, wherein the output signal is configured for use in generating an image of the scene.
