Since it began Cocconi Morrison, the search for extraterrestrial intelligence (SETI) has focused on interstellar classical communication. Recently, Berera:2020rpl pointed out that, at certain frequencies, photon qubits can retain their […]
![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.
