The biggest disappointment of this article is how it's just a mush of words without any real explanation as to how is it supposed to work while the original paper is obviously behind paywall.

The classical way is to visit sci-hub but it's new paper so it's not there yet. Googling works or doesn't work so it's not guaranteed and I didn't have much success with it in the past.

The real magic trick is writing an email to authors with polite request of a copy. More often than not they will send it.

Maybe we need a mush computer to solve what these words mean.

In my experience ChatGPT will look over a paper pull out numerous words which people generally don't understand and explain it all step by step... however I guess you could just tell it to write it like a tabloid or something.

[Overview]

>The essential idea of these analog devices, Goldhaber-Gordon said, is to build a kind of hardware analogy to the problem you want to solve, rather than writing some computer code for a programmable digital computer.

>For example, say that you wanted to predict the motions of the planets in the night sky and the timing of eclipses. You could do that by constructing a mechanical model of the solar system, where someone turns a crank, and rotating interlocking gears represent the motion of the moon and planets.

[Analog - Antikythra Mechanism]

>In fact, such a mechanism was discovered in an ancient shipwreck off the coast of a Greek island dating back more than 2000 years. This device can be seen as a very early analog computer.

[Back to the Point]

>Not to be sniffed at, analog machines were used even into the late 20th century for mathematical calculations that were too hard for the most advanced digital computers at the time.

>But to solve quantum physics problems, the devices need to involve quantum components.

[Crux of the advance]

>The new Quantum Simulator architecture involves electronic circuits with nanoscale components whose properties are governed by the laws of quantum mechanics. Importantly, many such components can be fabricated, each one behaving essentially identically to the others.

>This is crucial for analog simulation of quantum materials, where each of the electronic components in the circuit is a proxy for an atom being simulated, and behaves like an 'artificial atom." Just as different atoms of the same type in a material behave identically, so too must the different electronic components of the analog computer.

[Why is it important?]

>The new design therefore offers a unique pathway for scaling up the technology from individual units to large networks capable of simulating bulk quantum matter. Furthermore, the researchers showed that new microscopic quantum interactions can be engineered in such devices. The work is a step towards developing a new generation of scalable solid-state analog quantum computers.

So, basically an FPGA with quantum components. The interesting part is the scalable solid-state quantum components, imo, which to my knowledge don't yet exist.

We've been at it since 1982 when Feynman proposed it, based on the theory that Copenhagen is the functional truth of the universe. 41 years of research without a functioning prototype. Forgive me if I skip out for a few more and ignore sensationalist articles like this one.

Summary by ChatGTP

Physicists have created a new type of analog quantum computer that can solve problems in quantum physics that regular computers cannot. The scientists from Stanford University and University College Dublin found that the specialized analog computer, which has quantum components, can solve hard physics problems. The architecture of the computer involves metal-semiconductor components in a nanoelectronic circuit. The essential idea of the analog computer is to use hardware to solve problems instead of computer code. The researchers showed that the new design offers a way to scale up the technology to simulate bulk quantum matter.

Oh automated news items are already quite advanced. News outlets like NYTimes, Associated Press, probably Reuters and some others, have all made large investments in automation for content generation. AP has been doing that for many years, well before Chatgpt. But we should be very very skeptical of further automation of news generation because of the enormous potential for bias, either intentional or not. Imagine if Rupert Murdoch had an algorithm to write every news item with exactly the same slant that he decided when he woke up that morning - basically pairing AI with propaganda and putting huge power in a small number of hands. I am not looking forward to that replacement

I couldn't figure out if this statement meant that they found out how to increase the number of qubit works units ( like the number of cores, scaling out horizontally ) or if they mean that they can scale up the number of qubits that they entangled together ( scaling up the maximum size of the data type of a single instruction )

The unsolvable problem is that there are infinite parallel realities and free will allows you to select which reality you experience linearly

Fenrisvitnir t1_j7esnjf wrote

Thought experiment: if the quantum computer selects the one parallel reality with the answer you need to produce, as you say above, and does so merely by observation/wave collapse, wasn't the information obtained without expending work? That's zero point energy derived from the Heisenberg principle.

(hint: Hawking shows information cannot be destroyed or created without proportional energy preservation - https://en.wikipedia.org/wiki/Black_hole_information_paradox)
