IBM creates largest ever superconducting quantum computer
IBM claims it has created the world’s largest superconducting quantum computer, surpassing the size of state-of-the-art machines from Google and from researchers at a Chinese university. Previous devices have demonstrated up to 60 superconducting qubits, or quantum bits, working together to solve problems, but IBM’s new Eagle processor more than doubles that by stringing together 127.IBM’s 127-qubit Eagle processor now takes the top spot as the largest, and therefore theoretically most powerful, superconducting quantum computer to be demonstrated. Each additional qubit represents a significant step forward in ability: unlike classical computers, which rise in power in a linear fashion as they grow, one additional qubit effectively doubles a quantum processor’s potential power.
IBM has said that it hopes to demonstrate a 400-qubit processor next year and to break the 1000-qubit barrier the following year with a chip called Condor. At that point, it is expected that a limit on expansion will be reached that requires quantum computers to be created from networks of these processors strung together by fibre-optic links.

He does not speculate or making outrageous claim. He just stated Huawei take a position at start up laser company who work on excimer type of laser source Why is that fanboy ?
We know Huawei investment arm has invested in number of semi related companies specially in parts design and manufacturing of lithography machine. But this is the first that they also invested in laser power source

Not semiconductor. Debunked again.
Thats right. Im not an expert. But to claim that the fact that a single EUVlithography machine costing less and taking less time to built compared to a space station means that its easier to make, also doesnt make you an expert. In fact, its laughable. Otherwise, why hasnt china developed one already, despite producing space stations for many years now? And your materials argument doesnt prove anything.
I didnt say that china hasnt them. I said that chinese foundries dont have acess to Intel/TSMC suppliers.
Sure. But if chinese foundries dont have acess to these suppliers, this will be the key difference.
Because the priority was put in different places at different times. You can counter ask: if space stations were so easy how come Netherlands doesn't have a space station or even a rocket launch capability?
(with 5 nm process being another $5 billion or so) but if you count these R&D costs, you'd also have to count the R&D costs for the rockets and spacecraft materials for the space station which is rolled up in CNSA's budget.
My materials argument proves everything. The expense and expertise of materials testing to ensure chemical purity and resistance to contamination is exactly what "high quality materials" mean. You used those exact terms.
Spacecraft have those same low outgassing, low contamination requirements as part of their flight testing regime. But in addition spacecraft materials have the requirements for radiation hardness, thermal resistance and vibration resistance.
Btw, you ever wonder how I know these requirements for semiconductor equipment supply chains? I mean this stuff isn't exactly something you can pick up as an amateur, most people won't even know the terms to Google.
Ok. I guess i can accept that argument.
Not for me. But perhabs someone in this forum can say if china has all the materials technology to produce an EUVL machine.
SCMP article about the latest chinese supercomputers. I think that it shows some of the strengths and limitations of chinese semiconductor tech. What do you think of it?
you don't need to trust me, the key part of a EUVL machine is the optics, This is well known - EUV is a nonpenetrating but highly ionizing radiation, it is highly absorbed by all materials and thus can only be controlled by grazing incidence reflection, much like X-rays.
Take a look at the photo. It is huge. Assuming equal price per area (never is due to uniformity issues), the 412 mm mirror being 262x bigger is ~1 million USD. For a single mirror. The EUV optical system can have something like 10+ mirrors and precision motorized stages all in a vacuum chamber which probably contributes something like $20-30 million USD of cost.
(1) (2) on (3) was done.
The supercomputers are more algorithmic gains to my knowledge.
The domestic 28nm line was/is expected to be set up initially this year in 2021, with domestic 14nm plausible next year.
I believe you may have remembered wrongly.
DSP chip used for combat aircraft radars.
I feel that people place way too much emphasis on the antenna portion of a radar. You can have the best AESA antenna but if you have bad signal to noise ratio, you can’t pick out a target from the background noise. The brain of the radar matters just as much as the brawn.
