Subject: Re: Question Regarding History of Communications
The concept of direct counterfactual quantum communication is definitely not one for beginners in the field of quantum physics. Your interest in our field of work is greatly appreciated and I will do my best to explain. In the interest of avoiding complicated and frankly overly specific topics like photon states and detector cycles, this will be but a brief overview of DCQC's historical presence in our most enlightened State.
The main form by which we use DCQC centers around counterfactual quantum key distribution, which later simply became quantum key distribution. Quantum key distribution is useful for securing a channel between the sender and receiver. Its main value has never been its ability to send information; quantum key distribution is not graceful and requires a computer or mentat to use with any amount of efficiency. Instead, the interest was in a totally secure form of communications that could also detect eavesdroppers with no risk of being intercepted. As I'm sure you know, this was of great use in the State's early days, when unfaithful parties were searching for weaknesses everywhere.
It was never expected to become our primary form of communication, but in those days we believed our quantum entanglement program would succeed -- a valuable failure, I suggest you read the late Doctor Mantel's review on the project. Quantum key distribution is limited as once the sender and receiver are linked, they may never break away nor connect with any others. Furthermore, talking through it is like speaking through binary; one can only give a yes or no answer. Communication was less like speaking and more like fumbling for the correct question. It is good that QKD's have since been superceded by quantum pinpoint communication.
I am not sure if Executive Jones has gone over this with you, but a great flaw of quantum pinpoint communication is its accuracy. A device must know exactly where its target sits in order to communicate with it. This is where the old comes to save the new. Each fleet's flagship is equipped with an array of QKD's linked to its home fleetyard and every ship under its command. Using these as fleet locators, ships that have lost sensor function can still identify friendly vessels and keep a steady stream of information.
