The first application that comes to mind for me, and of course I am not a quantum physicist so its entirely possible that my conceptions here are misguided, would be with creating even more perfectly coherent beams of laser light for use in the high precision environments of quantum laser experiments. Possibly either at more affordable rates or to allow for an extremely temporally coherent wavefront in other shapes besides just the beam that is most commonly used? I could easily believe that there are potential experiments that are just waiting for the right technology to be viable.
