- Quantum Hardware is tough scale up (not impossible) due to decoherence of quantum systems, you need quantum error correction.
- Finding an application that justifies it economically (against SOTA methods in classical part) is hard except for a few areas, (Cryptography, simulation of quantum systems that are not already solved by classical simulation methods)
- Hype seems to be working (see the stock prices of several quantum companies after the announcement of Willow chip, one of which had only the word quantum in its name despite not being QC hardware company) (which I dont approve of)
