Image: Above is Figure 1 from the paper. Caption: Quantum communication with Q > 0, over distance L, is impossible at wavelengths where the horizontal line corresponding to L lies within the blue shaded region (summarizing the Milky Way ISM’s extinction curve). Gray regions are off limits from the ground. Adapted from [23, 26], with data from [30–37]. Credit: Latham Boyle.
