Quantum Relay

Overview

Through the discovery of an abiilty to measure a quantum state in such a way that it is left in a known state without breaking the entanglement, interstellar communications became possible through the use of a series of relay stations. This is known as a Schrödinger Event.   The basis of a Quantum Relay is a paired device that encases the two entangled particles in seperate chassis that have the abilty to measure and record the state of the entanglement creating the possiblity to perform near instintaneous communication.   Due to the costs involved, quantum relays are still rare, with only large orginizations able to afford the cost of the endpoints.  

Limitations

The nature of Schrödinger Event is that it is inherently unstable until the exact moment of measurement. This is worsened by any additional cosmic radition reacting with the system. For this reason, Quantum Relay stations are currently only capable inside of a planet's ionosphere.

Functionality


Prior to launch, the two ends of the Quantum Relay is synchronized in state and in internal timing. Each system is then put into a "listen" mode where it looks for a specific sequence of states that acts as a header and footer to the overall signal. This sequence is unique to the sytem, creating a serial numbered wrapper that can be used to confirm the system it came from.

To transmit, one end is put into a write mode where the data is sent by the unit in write mode creating a series of Schrödinger Events sent at a set timing. When these are detected by the system still in listening mode, it then capture the message, printing it out at the receiving station. Once the message is complete, the sending relay will automatically switch into listening mode to allow a return message to be sent.

Significance

Quantum relays are one of the most significant technologies in the Coalition of Allied Planets as it allows interstellar communication at a faster rate than using jump ships.
