>>11298947People don't understand quantum computing. It only affects algorithms in which you can superimpose every possible solution at once - for instance, suppose a bit is either 1 or 0. A qubit is hidden enough to be 1, 0 or both at the same time. If we had a password consisting of 50 bits (101011100...), a quantum computer could superimpose all 50 bits and find the solution with a single calculation, instead of having to brute force/test up to 2^50 solutions until you get the right one.
Unfortunately, this doesn't help in normal calculations. Setting up a convoluted superposition with qbits (converting it into an algorithm of 1's and 0's) to calculate the pythagorean theorem for a given triangle would be slower than using the same amount of normal bits. And we have trillions of bits to work with, whereas the greatest quantum computer today has 200 qbits or something.
So really, quantum computing only has effects on deep level programming where an algorithm would take N^12 complexity to solve otherwise. Which means cybersecurity will need to switch from an easily binary-fiable encryption standard to something more convoluted to prevent quantum decryption. Average consumer-grade programming will benefit none, and even if it did the average developer hasn't the slightest clue on how to understand quantum programming. They still haven't figured out multithreading.
Tl;dr Yeah, it's a shitty buzzword.
