Quantum computing stocks, including Rigetti Computing and D-Wave Quantum, have soared over 1,900% in the past year, fueled by investor enthusiasm for advancements in computing technology. Despite their market valuations surpassing $10 billion, these companies report minimal revenue, with Rigetti expected to generate approximately $20 million over the next year. Analysts are split on the outlook for these stocks. Proponents point to potential applications in fields like drug design and climate modeling as reasons for optimism. However, critics caution that the stocks may be overvalued, noting that they trade at more than 500 times their projected revenue.
