A small group of quantum computers have generated astronomical returns over the past year. One quantum company that has taken the market by storm is Rigetti Computing (RGTI 0.20%), which has seen its stock explode over 3,700% in just the past year. In the second quarter, some of the world's top hedge funds began piling into Rigetti, a potentially bullish signal. Ellis specifically highlighted the shifting sentiment at the Department of Energy's National Laboratories, which now appears to focus on quantum technology with clear business value. Hedge funds often trade on a short-term basis, which is not a good investing approach for retail.
