**Quantum Computing Stocks Surge Amid Growing Interest**

Pure-play quantum computing stocks, including IonQ (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), D-Wave Quantum (NYSE: QBTS), and Quantum Computing Inc. (NASDAQ: QUBT), have experienced significant price increases over the past year, with Rigetti Computing leading at a remarkable 545% gain. The Nasdaq Composite index, in contrast, rose approximately 19%. This growth is fueled by the burgeoning addressable opportunity for quantum technologies, projected to reach $1 trillion by 2035, according to The Quantum Insider.

Despite the impressive gains, historical trends suggest that these stocks may face challenges in the near future. Analysts warn of a potential bubble, similar to previous tech booms, with quantum computing still in its nascent commercial phase. Current sales projections indicate unsustainable price-to-sales (P/S) ratios above 30 for these companies, raising concerns about future corrections. JPMorgan Chase’s recent commitment of $1.5 trillion toward critical technology investments, including quantum computing, adds urgency to these discussions as the industry evolves.
