No. Actually it’s the extreme difficulty of making coherent light at short wavelengths and, if you succeed, material absorption. If you could overcome these, the quantum effects “help” you, because you have succeeded in making and guiding light at a smaller wavelength, hence miniaturization, which is everything.
