My Minifeed [1] started with a similar goal of having a "HN for blogs", but then it grew to include search, related recommendations, custom feeds, lists, etc. I don't have categories though.

Superconducting QCs are fast, but the state degrades incredibly quickly, so you only have a fraction of a second (maybe a millisecond at best, currently) until the entire state is garbage. Some other modalities like trapped ion are the opposite: state can live long, but each operation is orders of magnitude slower.

So, in that meme, the guy looks at one girl (the observed state) and "ignores" all other girls (all other possible states).

Think of all the "sales" that comprise such things as space missions (ones without immediate real-world use) or large hadron collider. Or any other large, expensive, long scientific project. If you measure the outcome purely in money within decades, these things can be said to be zero or negative profit.

How much profit was at the end of the chain of the current Artemis lunar mission? Well, zero or negative, but lots of companies and people up the chain made meaningful progress and made a living. Quantum computing is just like that in my opinion.

The biggest problem in my eyes is the "game" of commercialization. This technology is in early research phase, but it's so expensive and not immediately game-changing that the public funding was never enough. So, companies started to play the "we sell products" and "we do IPO" games, which IMO doesn't make sense.

(Often the research is done purely within clasically-simulated quantum computers, i.e. virtual QCs, but to verify and make the research publishable they need to run at least partial sub-problems on a real chip.)

Another, smaller, market is HPC centers. They buy and install quantum computers into existing HPC infrastructure because a) they have a few customers who need it (sometimes those same research institutions/universities), and b) they need to solve the integration problem for the future when QCs are actually used for real-world problems and big customers come to HPCs to run both classical and quantum high-performance jobs.

Here is an excerpt from my book I linked above, just to give a bit more context:

---

Since quantum computers are essentially analog devices that allow you to control, in a limited fashion, a set of quantum objects, you can do some research in foundational quantum physics. [...] Still, given the current state of the industry, classical computers outperform most quantum systems. But the research applied to smaller QCs can be scaled once the hardware scales.

Of course, the main area is quantum computing itself. From abstract, mathematical notions of algorithms to very low-level questions of calibration, many universities and research organizations are eager to have a quantum computer available to prove their theories and discover new properties. Commercial companies that deal with material science, battery technology, agriculture, and chemistry are buying quantum computers (or at least buying access to one) because they want to be ready if and when truly large-scale QCs become available. [...]

And finally, integration research. This is the least known and least discussed topic in the industry but is very important. Its significance is one of the motivations for writing this book. Quantum computers, being research tools, are not normal products. They are driven by software, like anything else, but this software changes rapidly and is rarely written with long-term evolution in mind. If you buy a quantum computer today, chances are your code will not work on any other quantum computer, or even on the next iteration of the same machine. At the same time, researchers often need to work with multiple types of machines simultaneously, and HPC (high-performance computing) centers, i.e. supercomputing data centers, want to integrate quantum computers into their existing infrastructure and provide a "quantum compute" service to their users.

I’ve made two attempts to explain the work we’ve been doing and to explain the current realistic state of the industry:

1. A talk at PyCon: https://youtu.be/tT1YLP5T71Y

2. A free ebook “ Quantum Computing For Software Engineers” https://leanpub.com/quantum-computing-for-software-engineers

The company I left a few months ago is planning its IPO this year. Like almost all other quantum companies, it’s gonna be a SPAC merger, not a pure IPO. Those traded companies mentioned in the other comments are mostly SPACs as well.

The criteria is simple: human-written (as much as I can validate myself), in English (for now), with valid RSS feed, and not a micro-blog (so, more than just feed of links or short tweet-like messages).

Similar to Kagi's Small Web viewer, or StumbleUpon-style viewer: you can get a random listing of blogs [1] or a random listing of posts from all blogs [2]. Feeds and posts are indexed, so full-text search works across all blogs. When possible and permitted by robots.txt, text is scraped for searching, so even if some text is omitted in the RSS feed by the author, search should work.

Though I do plan to implement a similar "view one random post at source" kind of view, soon.

UPD: Feel free to submit a blog, including your own! [3]

There were multiple court cases and this practice was found unlawful (and actually against EU law). But the government did not issue automatic refunds, and instead requested that people "actively appeal" with some time limits. They also refused to pay interest on the money withheld.

AFAIK, only about 50M Euro was paid back. A lot of funds gathered between 2002–2005 was never returned.

I've been living in Finland for 10+ years, and this whole story was super surprising for me to learn because the prevailing notion among people here is that Finland is the land of law, and everything is done correctly and legally, always, and we can and should trust the authorities.
