Nvidia CEO Jensen Huang's sobering assessment of quantum computing's timeline sent the space into a tailspin last week. During a question-and-answer session with analysts, Huang suggested that useful quantum computers were likely 15 to 30 years away.

Jensen Huang’s comments at last week’s CES about quantum computing being decades away stirred up discussion within the quantum industry.

Nvidia CEO Jensen Huang claims quantum computing is decades away, but is it really? The quantum era isn’t decades away — it’s unfolding in real-time.

Quantum computing holds the potential to radically transform the world. Nvidia CEO Jensen Huang and Meta Platforms CEO Mark Zuckerberg recently poured cold water on some of the hype surrounding 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.

Quantum stocks like Rigetti, IonQ and D-Wave Quantum saw steep losses after Nvidia CEO Jensen Huang said quantum computers are decades away.

Wave fell sharply after Nvidia’s Jensen Huang said that “very simple quantum computers” could be 20 years away.

Quantum Computing didn't have any news of its own to report, but the company is even smaller than D-Wave, with less than $1 million in revenue over the last four quarters. Its stock has soared even higher than D-Wave's over the last year, a disconnect that could lead to a continued decline in Quantum Computing's shares.

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.
