Quantum Shift Drive
More actions
Template:!SpacecraftQuantum Shift Drives are a high-speed Faster-than-light propulsion system primarily used in Florathel in which a spacecraft appears to "jump" instantly from one point to another. After the jump, the ship arrives at a precise destination up to 7,500 light-years away, beyond which accuracy rapidly decays. Utilizing very powerful computers fitted to a ship to calibrate the drive for each jump, the drive is among the fastest in the universe and can be fitted on individual civilian ships with recent improvements in energy storage.
Initially used by the Providence Union and other concurrent civilizations, the Shift Drive remains in use to this day. It is essential for interstellar trade, and many nations spend decent fractions of their budget on improving it further.
History
The first known examples of use of the Quantum Shift Drive was by the Providence Union, over 6 million years ago, although presumably other civilizations developed similar drives in the Elder Days. Over the intervening years, fairly rudimentary alternate forms were developed independently by other civilizations.
After Glanadi was discovered amongst the maze of stars in the Providence Cluster and the people of Florathel gained access to its archives, a very efficient prototype of the Quantum Shift Drive under development by the Union at its fall was uncovered. This form, which doubled the maximum effective jump range to 6,000 light-years, was quickly adopted by most nations across Florathel and its satellites. It was used to great effect in the War of Saiheran Succession, with great fleets abruptly materializing near targets before anything could be done to stop them.
The formation of the United Nations of the Florathel made it very easy for scientists to communicate across borders. This sped up the development of many technologies, but particularly the Quantum Shift Drive, which was refined to its present state, halving its energy use and improving external energy storage enough to allow placement on small civilian craft. Today, the Quantum Shift Drive can jump up to 7,500 light-years with virtually no positional errors. In intergalactic space, where exact positioning matters little, this range increases to 80,000 light-years before the craft starts going in completely the wrong direction.
Operation
The Quantum Shift Drive relies on a key facet of quantum mechanics, the fact that every possible event has a nonzero probability of occurring. The drive essentially takes the event of the ship changing position to the target and magnifies its probability through exceedingly complicated mechanisms that require 20 textbooks to explain.
This concept has been applied to other events such as the creation of new substances, but that requires far more computing power and energy to cause atoms to teleport across large distances from disparate locations into a new arrangement than to cause a group of atoms to teleport to the same location and remain in the same configuration.
Dangers
One potential danger in a hasty jump is that of rematerializing within a solid object. This causes the atoms of the craft to be bonded with those of the object, rendering the parts of the craft thus merged to be rendered immobile. This primarily occurs during hasty jumps or jumps to unknown regions of space, as the computer's calculations account for known objects and ensure that a ship does not impact anything as it rematerializes. This is still very unlikely, even neglecting calculations to avoid it, as space is famously very empty.
