Quantum computing will never be the future of computing. If we manage to make it work, it will at best be something like a TPU: a specialized processor for accelerating specific tasks. It will always be faster and easier to build more powerful classical computers than an equivalently fast quantum machine.

Quantum computing only solves a few specific problems. Like showing every possible outcome. For instance print(x), and your goal is to get a through z.

But if the problem is linear, like 2+2, it doesn't help to have quantum computing.

The experimental platforms that I am aware of that are been used to try and build quantum computers are based on condensed matter physics (superconducting junctions), atomic physics (trapped ions) or photons (quantum optics). None of this involves particle physics. The theoretical side of quantum computing, while a rich and deep field on its own, is an application of quantum mechanics and does not share any deep connection with particle physics.

It's speculation that it will ever be practical for computing, let alone in the near future. And even then I'm not sure how much that'll be related to recent experiments in high energy particle physics.
