Anyone who lived in USSR, or otherwise familiar with the way soviet authorities operate, would know not to trust any official data from USSR. I personally treat any statistics and data from the soviet government to be unreliable to the degree of meaninglessness.

So, in my eyes, there is no info available about the true health consequences of the Chernobyl catastrophe in Ukraine and Belarus.

It's pronounced "Ice eye".

According to the people I know from this company, the original use case was tracking the ice cover of the Northern seas, for both marine applications and climate research (the company is Finnish).

Every single discussion thread about any announcement in quantum feels exactly the same:

1. this is not what you think it is, there are caveats and the title is misleading.

2. I feel there is so much hype around quantum computing.

3. It's like nuclear fusion, always 10 years away.

4. Nuclear fusion is at least practical. QC is not.

5. Did they manage to find prime factorization of 17 already? LOL

6. Cryptography will be dead, RIP bitcoin and https.

7. No, actually quantum computers are useless.

It's tiring.

I recommend this recent post by Scott Aaronson https://scottaaronson.blog/?p=9668

I remember watching an interview with Marco Arment (creator of Overcast and Instapaper) where he mentions that he listens to Phish a lot [1]. He collects every single recording and live show, almost 30 gigabytes of music from this one band. IIRC, he listens to it when working, so he never runs out of "music for programming" this way.

Quantum networking is a lesser problem than changing the state and keeping intact long enough. You can already move quantum state over fiber optics pretty reliably, so transport exists, but what then? You need to put the qubits of the connected chip into the corresponding state (which takes time), and do it many times, and all that time is an overhead.

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.

The meme refers to the notion where an observation (i.e. interaction) collapses the wave function to a single value. As in, prior to observation, a system in a quantum superposition is said to be "in multiple states at the same time", and after the obsevation only one state exists, while all other possibilities are gone (or exist in other worlds, according to one of the interpretations of quantum mechanics [0]).

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

There is zero profit to be made at the end of the chain.

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.

During my 3.7 years at the company, we had dozens of sales of full-stack quantum computers, chips + cryostat + control electronics + software, ranging from 5 to ~100 physical qubits. Naturally, the buyers are mostly research institutions and univercities who need a real quantum computer to do research on quantum computation and simulation (to a lesser degree with the superconducting technology, though).

(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 worked at a quantum computing company that builds superconducting QC chips (so, not really applicable to one of the “bombshells” from the article). My team was designing the software stack which allows to control the QC, run quantum jobs/algorithms, and calibrate the parameters.

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.

On a similar note, I maintain and grow a manually curated collection of personal blogs with valid RSS feeds: https://minifeed.net/blogs

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]

Here in Finland this would cost about 50 euro, which is still a lot, but for me the main reason to never go to a movie theater again is that even after paying all of this money, the first 15 minutes is filled with advertisement, then 15 more minutes of movie trailers, then some "IMAX" or whatever intro video. By the time the movie starts, I feel like I've been watching tiktok for a day.
