I keep reading about Quantum computing and while I understand the use cases and the general operating logic, I still find it difficult to get how it works on a technical level (I've watched/read multiple explanation content pieces).

I wish there was something like Ben Eater's "Building an 8-bit breadboard" series for quantum computing. It's pretty dense, but even watching it on the second monitor did give a useful perspective on how CPU's actually work.

I don't think it's really a topic accessible by the layman right now at that level.

You need billions of dollars and thousands of hours to build and operate a quantum computer currently, and the cutting edge (i.e. the stuff that's getting close to being usable) has a large amount of information locked behind proprietary trade secrets.

There's several high level videos out there explaining it, but if you're looking for a nitty-gritty walkthrough like Ben Eater's videos, you're going to be waiting a good number of years, IMO

The high level videos are fine, but I haven't seen any content pieces that explain how quantum computers are built and operated from base principles. I recognize that there won't be any "build a basic quantum computer at home" types videos, but something that goes through the specifics of how a hardware qubit is built and how it operates with simplest use case possible.

If high level is fine for you, I'm pretty sure I've seen a few decent computerphile videos on the topic—they'll probably go as deep as you'll be able to get currently.

Not likely. These things are not a secret and they are accessible to most people in developed countries. The only prerequisites are an education, the will to learn and the library of a somewhat larger university nearby.

Have you watched computerphile before? They do generally go into a fair level of detail whilst trying to keep the content accessible.

And specifically OP was asking for something like a video series, as much as there will be some libraries out there with more detail, that's not what was asked for.
