The quantum mechanical phenomenon of entanglement can be utilized to beat the the Rayleigh limit, the classical bound on image resolution. This is done by entangling the photons that are used as the signal states. Using entanglement, the best possible image resolution is instead given by the Heisenberg limit, an improvement proportional to the number of entangled photons in the signal. Here, we present a novel application of entanglement by inverting the above procedure. We show that the resolution obtained by an imaging system utilizing separable photons can be achieved by an imaging system making use of entangled photons, but with the advantage of a smaller aperture. This results in a smaller, lighter imaging system. Smaller imaging systems can be especially valuable in satellite imaging where weight and size play a vital role. |
