The best is IBM's proven quantum tech which was recently published by HSBC. The bank uses IBM's quantum machine to estimate the bond prices which is proven to be more accurate than the standard machine. I'd rather buy IBM's share because many investment banks as well as government's treasuries will be using this vendor. What about insurance companies and healthcare sector?

Look what they just did with HSBC… Follow the money

https://www.hsbc.com/news-and-views/news/media-releases/2025/hsbc-demonstrates-worlds-first-known-quantum-enabled-algorithmic-trading-with-ibm Details aren’t much but that’s what I could find

I'd love to know what HSBC is using them for, cause they are literally unable to add 4 digit numbers, and are way slower in everything except for prime factorization (in theory, in practice still way slower right now). I believe it's just marketing hype with HSBC, there are literally 0 use cases for current qcs IMO.

Yeah I agree but HSBC is using their quantum comps already and they’re 10x better than a garage company like RGTI or Ionq who will likely die off. GOOG and IBM only real players in qc
