The newest innovation in faster-than-light communication, quantum communication utilizes a pair of particles - a proton and an antiproton - that are entangled, meaning a change in the proton reflects onto the antiproton, allowing for communication through the rapid ionization of the particles. Because the changing electron state in one the proton also affects the antiproton, the antiproton can be read using sensitive instruments and used to interface with conventional communications technology. Communication in this way is untraceable, unblockable, and undetectable, since there is no ‘signal’ being produced at all.
However, there are numerous disadvantages to quantum communication. Each pair can only communicate one-way through the proton, meaning that to have two-way communication, two pairs are required for just two devices to communicate with each other. Quantum pairs must also be physically produced with each other in order to be entangled, and they must be occasionally ‘recharged’ around once a month; this means that they are ineffective for most network-based communications at a distance. In addition, if one of the two devices containing a particle from a pair is destroyed, both particles are lost, meaning an entirely new pair must be created. And of course, the creation of quantum pairs is very expensive, usually around 15,000 Px or a single pair. It is possible to produce them by oneself, but it requires specialized equipment and expertise.
Quantum pairs can typically be housed in a tennis-ball sized device, which gets larger the more pairs are contained within. Quantum pairs are notoriously low bandwidth, unable to transfer larger amounts of data at once. This makes them ineffective at controlling drones or proxies.
