Methods of producing an optical surface atop an exterior of a substrate that includes smoothing the exterior using an ALD process to sequentially deposit ALD layers to produce one or more ALD films that fill spaces between spaced-apart asperities existing on the exterior, and thereafter depositing a reflective material on the smoothed exterior of the substrate to produce the optical surface.

Systems and methods for operating a quantum network system. The methods comprise, by a network node: generating optical clock pulses and photons using the optical clock pulses; generating a combined signal by combining the optical clock pulses with at least some of the photons such that a consistent temporal offset exits between the optical clock pulses and the first photons and/or a wave function of each photon at least partially overlaps an envelope of a respective one of the optical clock pulses; and transmitting the combined signal over a first quantum channel in which the optical clock pulses co-propagate with the photons.
A spectrographic system includes a space-borne spectrometer in communication with a ground-based processor. The space-borne spectrometer may include an interferometer, a detector array downstream from the interferometer, and a spectrometer controller configured to cooperate with the detector array to collect Fourier Transform Spectral (FTS) data, generate Principle Component Analysis (PCA) scores from the collected FTS data, generate an approximate interferogram based upon the PCA scores and the collected FTS data, generate residuals based upon the approximate interferogram, and generate compressed FTS data based upon the PCA scores and residuals to be sent to the ground-based processor.
