Quantum-computing stocks are lower, and although they’re small and not making much money, an escalating trade war could complicate their businesses.

For example, last month when Nvidia CEO Jensen Huang said useful quantum computers would be ready about 20 years from now, longer than some investors had hoped, stocks like Rigetti and D-wave sank more than 30% in one trading session. Companies like Microsoft are less likely to be as sensitive to these sorts of messages.

Investors are always on the lookout for the next big thing, and following the success of AI in recent years, it’s no surprise to see stocks in

High-risk and potentially high-reward quantum computing stocks include Rigetti Computing, D-Wave Quantum, and IonQ. Established players such as Google parent Alphabet, Microsoft, IBM, and Honeywell are also quantum computing leaders.

The Nvidia CEO, who made Elon Musk and Larry Ellison "beg" for more AI GPUs, argued that quantum computing remains unreliable. Huang said that “very useful quantum computers” are probably two decades down the road.

Quantum computing is still in its infancy but holds significant potential to transform industries, particularly when integrated with artificial intelligence (AI). Unlike traditional computers, which process data using bits that can be either zero or one,
