Computers are ubiquitous in Star Wars. Are they quantum-level in terms of complexity?

    Why assume that quantum computing is the in-universe end point of computer technology? Look for some evidence, document what you can, and then ask if someone else has more information. Commented Mar 25, 2016 at 16:36

    The laws of physics are perhaps different in the Star Wars universe than in our own (for example, there's sound in space) so we can't be sure quantum physics would work the same or allow for faster computations. Although in The Force Awakens when Finn first returned to the Star Destroyer, I thought I did here them say some bit of technobabble about "quantum" something over the PA system in the hanger.

    Hi, I have edited your question to remove the comments about assuming the computers are quantum. I think it is an ok question, but this is a better way of phrasing it maybe. Commented Mar 25, 2016 at 16:48

    @Daniel Roseman - "Luke, you switched off your targeting computer. What's wrong?" Other lines from the New Hope script here include "the Death Star plans are not in the main computer" and "It'll take a few moments to get the coordinates from the navi-computer."

    Considering the time it takes to calculate a jump to light speed, probably not.

Some computers and devices in Star Wars have used "quantum" as part of their description or design:



  • Quantum computer: appears in the Death Star novel in the context of cryptography:

    In addition to the best military wards and pyrowalls, the folder was also protected by a random number generated by a quantum computer, said number being forty-seven digits long. Moreover, the program would shift each digit one value lower or higher every six standard hours, and only somebody with the code to access the program running it could keep track of this shift—one had to know the date and hour the program generated the number in order to follow the sequence. It was a slow and unwieldy process, hardly suitable for files that needed to be accessed with any frequency, but workable for him.

    Death Star (2007), chapter 34; emphasis added

  • Quantum RAM: appears in the novella A Forest Apart as part of an advanced droid's specifications:

    [One-twenty?] the droid scoffed. [Don't insult me. My processor speed is fifty-point-three-two times faster than the one-twenty's.]

    [Then you must have the GwendoLyn Six,] Chewbacca said.

    [That's right,] the droid said proudly. [Tachyon processing bands, quantum RAM, biocell storage.]

    A Forest Apart, printed in Tatooine Ghost, page 446; emphasis added

Overall, it seems like quantum computers do exist in Star Wars, but tend to be used for specialized purposes, implying that most computers aren't quantum in design.
