Shares of Rigetti Computing (RGTI) soared 5% in pre-market trading on Wednesday, as investor enthusiasm for quantum computing stocks continues to drive volatility in the sector. This latest move comes amid a broader trend of speculative interest in quantum computing companies, which has seen some stocks in the sector rise by 100% or more this year.

Rigetti, part of the so-called "Quantum 4" group of pure-play quantum computing stocks, has been on a roller-coaster ride. The stock has seen dramatic price swings, having risen from as low as $1.06 to a recent high of $58. Despite the company's limited revenue and lack of profitability, investors appear to be betting on the long-term potential of quantum computing technology.

The surge in Rigetti's stock price comes as major financial institutions and tech giants are increasing their focus on quantum computing. Recent announcements, such as JPMorgan Chase's plans to invest up to $10 billion in strategically important sectors including quantum computing, and IBM and HSBC's development of a quantum-based algorithmic bond trading platform, have fueled investor interest. Additionally, speculation about potential U.S. government funding for quantum computing companies, although not confirmed, may be contributing to the positive sentiment surrounding stocks like Rigetti.
