Quantum Computing Inc. (QUBT) and Rigetti Computing (RGTI) are both active in the quantum computing sector, with QUBT focusing on enterprise software and AI integration while recently launching its Dirac-3 Entropy Quantum Computer. Though QUBT’s revenue remains negligible, it has secured $293.6 million through recent capital raises. In contrast, RGTI reported significant revenue in its latest quarter, 50 times that of QUBT, bolstered by its 84-qubit Ankaa-2 system and ongoing developments toward a 336-qubit system.
As of April 2025, QUBT has raised $93.6 million and secured a $200 million private placement, enhancing its cash position to over $350 million. Meanwhile, RGTI has $237.7 million in cash following a strategic investment. Notably, QUBT’s shares surged 2336% over the past year, significantly outpacing the S&P 500’s 19.4% increase, while RGTI’s shares rose 1116% during the same period.
Both companies currently share a Zacks Rank #3 (Hold), but RGTI is recommended as the stronger near-term option due to higher revenues and clearer technical advancements.
