Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has a repeating structure in time

Can quantum computing save us from 500 missiles attacking simultaneously? Perhaps ... and it has a far better shot than classical computers, say these companies.

The third unpleasant truth that investors of IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. will have to face in 2026 is that the barrier to entry for this industry is almost certainly lower than they realize.

Quantum computing represents a potential breakthrough technology that could far surpass the technical limitations of modern-day computing systems for some tasks. However, putting together practical, large-scale quantum computers remains challenging,

Quantum computing company D-Wave has announced deals with Florida Atlantic University (FAU) and a “leading Fortune 100 company” for a combined commitment of $30 million. The $20m agreement with FAU will see the university acquire and install an Advantage2 quantum computer at its Boca Raton campus.

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.

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.

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.

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