Are any of these worth investing in at this point?

I've been researching a few high-growth/speculative tech stocks recently and wanted to get some opinions from people here who follow the sector more closely. I currently have investments in the FTSE All-World (Acc) but want to diversifya bit more. The main companies I've been looking at are: lonQ (10NQ) D-Wave Quantum (QBTS) Palantir (PLTR) Broadcom (AVGO) TSMC (TSM) I'm especially interested in the long-term potential of quantum computing companies like lonQ and D-Wave. understand they're still early-stage, unprofitable, and highly speculative, but the projected growth rates and future market potential seem huge if quantum computing becomes commercially viable over the next 10-20 years. Palantir also caught my attention because of its Al/data analytics positioning and strong projected growth, although the valuation seems pretty aggressive already. For those with more investing experience: Do you think these are genuinely strong long-term investments? Are quantum computing stocks still too early/risky to invest in seriously? Which of these would you actually buy vs just keep on a watchlist? Do you see any of them becoming the "next Nvidia"-type winner, or is that mostly hype?
