In addition to the well-understood requirements of transmission distance and data rate, for quantum networks to be useful in a real-world setting there are at least two other requirements that need to be considered. One is real-time network control, specifically time-sensitive networking. The second is cost. Tue, 31 Aug 2021 11:19:26 EDT //www.koonmotors.com/releases/2021/08/210831111926.htm
