content: They did the 'we got one too' schtick with a stealth fighter jet as well. Surprisingly the USAF is about 20 years ahead of consumer commercial tech on occasion, sometimes more, but the Chinese are decades behind whats even commercially available more often than not. They didn't even build half the stuff they currently operate, its all old repainted Russian technology and/or derived from Russian technology because they don't know how to do it themselves. Anyone who did develop any kind of quantum technology is going to keep it under lock and key because that kind of technology is going to allow them to dominate the battlefield for decades to come, quantum radar in the next decade would be like having cheat codes against current air superiority doctrines used all over the globe. It's a multi-trillion dollar industry in the U.S.-- so it would fuck American wallets real hard. China and India are at least 40-50 years behind, and that's with China stealing everything they can get their hands on. So this is a just a political card played by chinese politicians on their own populace while making them look stupid abroad. DARPA will have a meeting over coffee about it, submit a short memo to the Pentagon, then go back to trying to make mutant/machine-aided super soldiers.
