Quantum Communication
« on: April 23, 2020, 16:53:20 »
Quantum Communication is touted in this article that this technology would make US subs more lethal.[ Researchers at U of Ottawa]

University researchers have discovered that quantum communications are possible with submerged objects in turbulent water. The revelation means it might someday be possible for the National Command Authority to use quantum communications to securely communicate with underwater submarines, particularly those that make up part of the nuclear triad.

According to IEEE Spectrum, researchers at the University of Ottawa have demonstrated their ability to transmit information by quantum communications across thirty meters of “turbulent” water. The researchers were able to send 72 kilobits of data per second—or the equivalent of 4,600 characters per second. Although the method has been used to send and receive data through water in the past, it has been used across calm water and not necessarily water representative of a real-world marine environment.

The Very Low Frequency (VLF) radio waves we used in the mining exploration business were meant for the submerged subs. After a few months they release the properties of those waves and we would compare that to the data that we collected in the field to determine if there was any reflection or alteration being caused by localized ore bodies.
