Rigetti's “one-stop shop” for quantum computing could grow over the next few years. Quantum Computing's photonic chips could disrupt the older quantum players.

As of mid-October 2025, pure-play stocks IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. had soared by as much as 6,200% on a trailing 12-month basis. Although quantum computers offer intriguing real-world use cases, this technology is years away from solving practical problems more cost-effectively than classical computers.

Unlike most quantum computing stocks, Quantum Computing underperformed the market last year. Sales still may have doubled in 2025, and sales could triple in 2026 -- and quintuple in 2027.

Even compared to its closest competitors, Quantum Computing stock is extremely expensive. The company has quadrupled its share count over the last three years to raise money.

Quantum pure-plays have accrued massive market capitalizations despite minimal revenue. Despite industry hype, many experts suggest practical quantum computing applications remain a decade or more away.

At select points last year, trailing 12-month gains for quantum computing stocks IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. reached as much as 6,200%! Investors have become enamored with the sky-high addressable market and investment potential of quantum computing.
