Does Terra Quantum AG break AES and Hash Algorithms? According to this Bloomberg article:

A Swiss Company Says It Found Weakness That Imperils Encryption
Terra Quantum AG has a team of about 80 quantum physicists, cryptographers and mathematicians, who are based in Switzerland, Russia, Finland and the U.S. “What currently is viewed as being post-quantum secure is not post-quantum secure,” said Markus Pflitsch, chief executive officer and founder of Terra Quantum, in an interview. “We can show and have proven that it isn’t secure and is hackable.”
The company said that its research found vulnerabilities that affect symmetric encryption ciphers, including the Advanced Encryption Standard, or AES, which is widely used to secure data transmitted over the internet and to encrypt files. Using a method known as quantum annealing, the company said its research found that even the strongest versions of AES encryption may be decipherable by quantum computers that could be available in a few years from now.
Vinokur said in an interview that Terra Quantum’s team made the discovery after figuring out how to invert what’s called a “hash function,” a mathematical algorithm that converts a message or portion of data into a numerical value.

We have already had limitations due to Grover's Algorithm that are asymptotically optimal. Are we going to have another snake oil sale like Treadwell Stanton DuPont?

Update: It turns out a product advertisement that we don't buy it!

The onus is on the company to prove their claims, especially when they are extreme. There is also no financial motivation to not prove their claims. I can understand if they say that they want to keep their new &quot;unbreakable algorithm&quot; secret until they patent it, but what reason in the world would there be to not present a break? This is especially the case since it's not something that can be utilized now. Unless, that is, they claim that they can break AES using today's quantum machines in which case I really have to hold back from writing expletives.
In short, this has all of the smell of snake oil with all the motivations of a company trying to get a lot of press and attention, and doing damage while they are at it. It's unfortunate that people don't think that they can make money while keeping their basic ethics.
Of course, one could argue that how can I make this judgment without having seen the details. I guess I'm old enough to not care to be wrong with a 1 in a $2^{40}$ chance. (I just made up that probability but without publishing how I got to it, I guess that no one can challenge me.)
