Monday's tech sector meltdown, triggered by DeepSeek's AI breakthrough, caused collateral damage to share prices in the quantum computing space. When Nvidia plunged by 17% on fears that future AI models might require far fewer premium chips to train and operate than expected,

Trapped-ion quantum computing leader IonQ (NYSE: IONQ) is emerging as a potential leader in the commercialization of quantum computing through its trapped-ion technology approach. Unlike traditional superconducting quantum competitors,

Amid stock-market jitters, quantum computing start-ups continue to make progress — and to score hundreds of millions of dollars in investments.

Quantum computing has been on the horizon for what feels like decades. But with the explosion of artificial intelligence (AI) over the past year or so, the quantum computing future could be upon us. In 2025, there are several stocks that could benefit. Some are big tech businesses; others are specialty start-ups focused on a particular niche.

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 stock has surged amid the quantum computing hype but faces skepticism due to its track record. Explore more details here.

One of these companies' quantum platforms can complete calculations in minutes that would take today's supercomputers longer than the age of the universe to solve.
