I worked at a quantum computing company that builds superconducting QC chips (so, not really applicable to one of the “bombshells” from the article). My team was designing the software stack which allows to control the QC, run quantum jobs/algorithms, and calibrate the parameters.

I’ve made two attempts to explain the work we’ve been doing and to explain the current realistic state of the industry:

1. A talk at PyCon: https://youtu.be/tT1YLP5T71Y

2. A free ebook “ Quantum Computing For Software Engineers” https://leanpub.com/quantum-computing-for-software-engineers

The company I left a few months ago is planning its IPO this year. Like almost all other quantum companies, it’s gonna be a SPAC merger, not a pure IPO. Those traded companies mentioned in the other comments are mostly SPACs as well.
