Quantum Computing Stock Showdown: D-Wave Quantum vs. Rigetti Computing

D-Wave Quantum and Rigetti Computing are two companies in the quantum computing industry. D-Wave has a strong start in 2026 with the acquisition of Quantum Circuits, which fills a gap in its offerings. Rigetti uses gate-model technology and has a vertically integrated tech stack, but its sales have declined, resulting in a significant operating loss in 2025. Both companies have potential, but D-Wave may be a better investment due to its recent acquisition and expanded offerings.
