I recently watched a documentary about quantum computing and got curious about the space from an investing perspective. [https://www.youtube.com/watch?v=1\_gJp2uAjO0](https://www.youtube.com/watch?v=1_gJp2uAjO0)
I did a bit of research with ChatGPT and the names that stood out most were IonQ, Quantinuum, Rigetti, D-Wave, IBM, Google and Microsoft. IonQ seems to have strong commercial momentum, Quantinuum looks very strong technically, while IBM/Google/Microsoft feel like safer ways to get exposure without betting everything on one quantum architecture.
What I’m still struggling with is understanding which technology will actually win long term — trapped ions, superconducting, photonics, neutral atoms, etc. Curious to hear from people following the sector closely: what companies or technologies do you think are genuinely ahead, and what am I missing?
