Ahhhhhh, I think I get what's going on here. You're a conspiracy theorist about whether quantum computers will ever become powerful enough to crack RSA or whatever else. You know they never will. You know the truth. You have the secret knowledge.

And all these companies and scientists with PhDs and whoever else are just wasting their time and throwing money in a furnace. They're doing it to enrich themselves or to generate hype or for job security, but you know the truth that it will never become actually useful.

This explains your focus on any negative fact or instance of hype or prediction that didn't pan out. These things confirm your beliefs.

Hey, it's a free country. You're entitled to your opinion. Again, those who say something can't be done should not interrupt those who are doing it.

Ok, sure. People hype the potential usefulness of their research too. It seems like you're expecting every research direction of a complex new technology like quantum computers to quickly pan out. That's unrealistic. I also don't get why this bothers you so much. Superconducting quantum computers use Josephson junctions, and a few of those exist. But it doesn't matter: Even if that technology was a dead end, there are still other viable ways to build quantum computers, some of which might have more favorable properties.

There is actual progress in the number of low error qubits in these computers, in how long they can maintain entanglement, and so forth. It's hard. Smart people with funding are working on it; they'll figure it out if they keep at it. It takes time. If people oversell the potential future usefulness of early research, that's unfortunate, but I guess it's part of the game.

If Wikipedia is right, there wasn't a working quantum gate before 1995 nor a working quantum computer before 1998. Both are more recent than 35 years ago. Any speculation about the capabilities of quantum computers 35 years ago prior to an actual physical realization would have been theoretical.

Those who say something cannot be done should not interrupt those who are doing it. If research into quantum computing continues, I have no doubt they will eventually figure out how to make a useful quantum computer. This stuff is really hard; it's not surprising that it takes a lot of time, funding, and expertise. Hopefully they create neat spinoff technologies along the way.

I have heard the empty promises of QCs for 35 years now

The amount of hype in news articles about scientific discoveries is unfortunate but not particularly surprising. Given your user ID, I would have expected you to be aware of this. Per https://en.wikipedia.org/wiki/Timeline_of_quantum_computing_and_communication, the first quantum logic gate was built in 1995 (30 years ago), the first quantum computer—a whopping 2 qubits—in 1998 (27 years ago). If anyone was talking about what quantum computers could do 35 years ago (1990), it was pure future-looking theoretical possibility and nothing more.

Apparently not. From https://thequantuminsider.com/2025/10/24/forthcoming-ibm-paper-expected-to-show-quantum-algorithm-running-on-inexpensive-amd-chips/,

But qubits are fragile and they can lose coherence or produce calculation errors from the slightest environmental interference, making error correction one of the biggest challenges in building reliable quantum systems. IBM’s algorithm, first announced in June, is designed to detect and correct these errors dynamically while the quantum chip is running, allowing for continuous and stable operation.

According to IBM, the experiment shows that its algorithm can run effectively on AMD’s reprogrammable chips — hardware that is common in data centers and embedded systems — rather than on specialized quantum control units.

and

The research suggests a path to building hybrid quantum-classical systems that can operate with lower costs and faster development cycles.

It sounds like the error correction algorithm takes in data about the qubits and suggests some way to manipulate them to correct errors. So qubits still need to be monitored and manipulated, but the procedure for doing so can be computed on conventional hardware.

I think every ballot should have a "none of the above" option.

I am guessing you don't vote? They do have that option. It is called the write in candidate. Traditionally, Mickey Mouse has been the winner throughout the years. That mouse eventually became so popular that they stopped reporting on it after he hit over 20% of the vote back in the 90s.

The salient point is the requirement to redo the election with all new candidates if "none of the above" achieves plurality. The goal is to force the parties to run candidates that actually appeal to ordinary people.

It does. You can choose not to vote and that is usually the largest proportion of eligible voters.
