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.

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

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 computing stocks sank on Wednesday, pausing a year-long rally, after Nvidia CEO Jensen Huang said the technology's practical use was likely two decades away.

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

The shares of IonQ Inc. and other companies linked to quantum computing tumbled in extended trading on Tuesday after Nvidia Corp. Chief Executive Officer Jensen Huang said “very useful” quantum computers are likely decades away.

One of Wall Street’s most speculative trades just had some of the froth wiped out in dramatic fashion. The outlook is looking murky from here onwards.

First, D-Wave Quantum CEO Alan Baratz said that Huang was “dead wrong.” He said that his company is “commercial today,” and its services are be
