Quantum computing could be the next major technological breakthrough. While many tech giants are developing quantum systems, there are also a few pure-play quantum computing companies -- and one has been getting significant attention recently.
That would be Rigetti Computing (RGTI 4.22%), which develops superconducting quantum computers. Rigetti's up 61% year-to-date as of Dec. 24, and recent SEC filings show that it has been a popular investment.

Key Data Points
Just because the big money is buying a stock doesn't necessarily mean you should do the same. Their risk tolerance and investing strategy could be different than your own.
And Rigetti is a risky stock. The company doesn't make much money, considering it has an $8 billion market cap, with trailing revenue of $7.5 million. Rigetti is also far from profitability, with a recent annual net loss of $351 million.
If you're bullish on quantum computing, Rigetti may be a good fit for your portfolio, but based on the risk and the extremely high valuation, consider starting with a small position.
