Entangled Satellite

An Entangled Satellite is an artificial survey satellite built with quantum communicative devices capable of communicating over essentially infinite distances instantaneously by quantum entanglement. Reverie uses three of these satellites, launching them into orbit around Alpha Centauri A b, Proxima b and Proxima c. The electronics are powered by both collapsible solar panels as well as a radioisotope thermoelectric generator. The satellite is also equipped with a variety of survey / research equipment for studying their intended celestial body.

Quantum Communicative Device
The Quantum Communicative Device or QCD is a brilliant machine that is used to transmit data via a physical phenomenon known as quantum entanglement. Essentially, the machine keeps 2 entangled particles within a sealed cylinder, which is bound to its opposite particle on Earth. The way research data is transmitted is by changing the spin of the particle, thereby changing the spin of its entangled partner on Earth. By this method, the spin (Either an integer spin or half integer spin) can be detected and read as binary code, an integer spin being 1 and a half integer being 0. This manner of communication is unfortunately very slow, as only one particle is present to give information, and sometimes that information is not transmitted at all.

The strategy the engineers used to ensure that the data was properly transmitted through entanglement is to keep attempting to strike the particle until the desired spin is reached, and then have the confirmation transferred back from Earth to the entangled particle within the satellite to let it know that the information has successfully been transmitted. When the data has been transmitted, the second particle is flipped, and the next set of information can be transmitted, and the cycle repeats.

There are only two particles per satellite as it was incredibly hard to get just two particles trapped within a magnetic field in the satellite. More advancements in this sort of technology will be coming in the future.
