While timelines remain uncertain, early investors are positioning for a future where quantum computing plays a meaningful role alongside classical and AI-driven systems. Here are the top quantum computing stocks to consider for 2026—and what to know before investing in this emerging technology.

Amazon is boosting its quantum computing bets with Peter DeSantis, its new leader for AI models, custom silicon (semiconductor chips) and quantum computing. DeSantis is a 27-year Amazon veteran who will oversee the three areas as "naturally reinforcing," according to a company note.

Diamonds might be the next big thing in quantum computing. Quantum Brilliance now grows ultra-pure diamonds for better quantum sensing and portable quantum computing.

D-Wave Quantum (QBTS) stock jumps after a $20M Florida Atlantic University deal for an Advantage2 quantum computer and new HQ—get the latest update now.

Small, pure-play companies and tech leaders are involved in this field.

Nvidia isn’t building quantum computers, instead it’s using its supercomputing strengths to accelerate quantum computing research and commercialization.

Simmons says that silicon quantum processors offer an inherent advantage in scaling, too. Generating numerous registers on a single chip and using “naturally occurring” qubits, she notes, reduces their need for extraneous confinement gates and electronics as they scale.

Researchers from the University of Waterloo's Faculty of Science and the Institute for Quantum Computing (IQC) are prioritizing collaboration over competition to advance quantum computer development and the field of quantum information.

Quantum computing is forcing crypto to confront an existential security test. Three networks are already demonstrating preparedness.

Quantum technologies are supposed to revolutionize the way we calculate, communicate, and measure. But where do we really stand?
