Can all be substituted with Chinese or Japanese products. Japan is basically an open supplier, even selling to the Soviets historically. Japanese example: Shimadzu

Chinese suppliers are basically held back solely by market momentum, just as you saw with the semiconductor sector, not any technical issues.

Simple example: United Imaging which makes full body MRI, one of the most complex scientific instruments in the world with complexity on par with jet engines and supercomputers. Now one of the largest MRI suppliers in the world.

Commercially available scientific instruments are also not on the cutting edge - those are custom built as one of a kind tools. They're for QC or process analytics. And for those, many non-technical features are considered ie service and price.
Sleepy34 is such a fool. By the same logic, China could hurt the American auto industry badly because the US uses so many Chinese auto parts like tires, windshields, etc. Same can be said for many other industries of the US, too.

Keep this troll around is doing more harm than good to the forum.

All capital inputs in general, actually.

The thing is - the export controls are simply part and parcel of breaking fundamental research capabilities in China. The US has leading positions in all kinds of scientific tool and precursor manufacturing - Agilent, ThermoFisher, Keysight, Sigma Aldrich, Millipore, Xylem, Waters Corp., etc - and so by harming the inputs used in Chinese scientific industry, they will cause reduced scientific productivity for years until China can catch up (even assuming China doesn’t get galapagosed).
Ever heard of RIGOL? It is a Chinese company which makes alternative better spec and cheaper products for the segments Agilent (now Keysight) used to sell in.

Siglent is another Chinese company in the same segment.

There are Chinese companies for every single relatively mass market scientific tool.

That's some fancy lawyer tongue for "We made it harder for you and you took it like a training exercise to become self-sufficient." The politicians got to say that they stuck it to China, but they burned their own fields on the way out leaving the next generation of US politicians to face a much stronger and self-reliant China.
(even assuming China doesn’t get galapagosed).
LOL What wishful thinking! When has that ever happened despite the countless desperate attempts from America? When has China ever failed to develop a technology denied to it? Many places are insulated but know what's so special about the Galapagoes Islands? They're small as hell. Know why they don't call it "Australia-ized?" Because even that is way too large to be isolated not to mention a China that is the largest innovation tech country in the world.
For example, if you look at the instrumentation and materials used by Chinese chemistry labs, U.S. inputs are absolutely pervasive.

Try it. Lose a tentacle every time you reach out with it as a weapon. America never learns from the past and I wouldn't have it any other way.

China plans to launch an ultra-secure global communications service by 2027, integrating its quantum satellite constellation with ground-based networks. Led by physicist Pan Jianwei, known as the "father of quantum", the project aims to provide practical large-scale quantum communications within the next decade..

"Chinese Scientists Report Using Quantum Computer to Hack Military-grade Encryption​

  • Chinese researchers, using a D-Wave quantum computer, claim to have executed what they are calling the first successful quantum attack on widely used encryption algorithms, posing a “real and substantial threat” to sectors like banking and the military, as reported by SCMP.
  • The D-Wave Advantage, initially designed for non-cryptographic applications, was used to breach SPN-structured algorithms but has not yet cracked specific passcodes, highlighting the early-stage nature of this threat.
  • Despite the advance, the researchers acknowledge limitations such as environmental interference, underdeveloped hardware and the inability to develop a single attack method for multiple encryption systems still hinder quantum computing’s full cryptographic potential. "

What would be some uses of this type of network? Would it be primarily for military purposes? Or financial transactions?
