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.

Quantum Computing shares fell by around 23%, while IonQ stock was down by more than 12% mid-day Monday. The previous week, the stocks also tanked after Nvidia chief executive Jens

Throughout the current AI boom, quantum computing companies have quietly been making advancements, offering previews as to what the next phase of technology could look like. Huang

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.

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

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 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.

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
