A quantum capacitor (also referred to as an QC, or a q-chip) is a device that stores information in a quantum field. It is a passive electronic component with two terminals. The effect of a quantum capacitor is known as quantum capacitance, which at the most basic level is the ability to store and discharge quantum information at desired rates.
QCs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, batteries, imprinters, non-localized recorders (NLRs), quantum navigation, Chronoscopes, entanglement arrays, and indeed Dyson Spheres are now inextricable parts of the structure of modern life, made possible by ubiquitous applications of QCs.
Quantum capacitors were the result of military research programs initiated during the Third World War in direct response to the Thanksgiving attacks. These R&D programs sought to create a means to detect seemingly undetectable swarms of small projectiles launched at random intervals to strike a single target, better known as "pebble mobs". The first quantum capacitor was successfully tested in 2056 as part of the Argus program that led to the launch of the Quantum Acquisition Object Detection (QAOD) system. However, the technology was not declassified until the 2060s when it was employed by NASA for the FTL project.
