Key Points Quantum computing stocks D-Wave and Rigetti have seen double-digit drops year to date. Both D-Wave and Rigetti are not profitable but have amassed large cash hoards on their balance sheets. D-Wave is growing bookings, while Rigetti captured a big customer order in 2026. Quantum computing has the potential to transform technologies such as artificial intelligence (AI). It can process complex data in minutes that would take centuries for a conventional computer. The sector sparked strong investor interest in 2025, but the "great rotation" of 2026 changed the situation. Wall Street shifted away from tech stocks with sky-high valuations this year, which includes the nascent quantum computing industry. Will AI create the world's first trillionaire? Our team just released a report on the one little-known company, called an "Indispensable Monopoly" providing the critical technology Nvidia and Intel both need. Continue ยป This creates a potential buy opportunity for once-hot stocks D-Wave Quantum(NYSE: QBTS) and Rigetti Computing(NASDAQ: RGTI). The former's share price is down 47% this year through the week ending March 27. Rigetti dropped 40% in that time. But if you had to pick only one, which is a better investment in the quantum computer field? Here's an examination of both to arrive at an answer. Rigetti Computing Rigetti uses gate-model technology for its quantum computers, a popular approach in the sector since it allows for precise control over quantum machines. The company seeks to solve some key industry challenges, such as enabling scalable systems. Rigetti's competitive advantage is a vertically integrated tech stack, enabling end-to-end execution of the construction process. Its in-house Fab-1 manufacturing process permits quick iterations in the design and building of quantum computer chips. The company's vertical integration strategy seems sound, yet it hasn't led to much revenue. It ended 2025 with $7.1 million in
