Quantum computing stocks have been losing ever since Nvidia chief executive Jensen Huang said widespread applications of quantum computing are still decades away. But investors are rewarding these companies once again on Wednesday after Microsoft Corp (NASDAQ: MSFT) made a statement that starkly differs from Huang’s view on quantum computing.

Therefore, Huang's prediction that quantum computers won't go mainstream for 15 to 30 years sounds reasonable. It took Nvidia about two decades for its gaming and professional visualization graphics processing units (GPUs) to evolve into AI accelerators for data centers.

Shares of Rigetti Computing (NASDAQ: RGTI) climbed 7% as NVIDIA (NASDAQ: NASDAQ:NVDA) announced plans to host its first Quantum (NASDAQ:QMCO) Day at the GPU Technology Conference (GTC) 2025, sparking enthusiasm in the quantum computing sector.
