Better Quantum Computing Stock: Rigetti Computing or IonQ?

Core Viewpoint - Quantum computing stocks remain highly volatile, with companies like Rigetti Computing and IonQ experiencing significant price fluctuations, including a 70% drop for Rigetti shortly after reaching an all-time high [1][2]. Company Analysis - Rigetti Computing reached a new all-time high at the end of 2024 but fell 70% in early 2025, currently down about 40% from that peak [1] - IonQ has also faced volatility but not to the same extent as Rigetti [1] - Both companies rely on external funding, issuing shares and taking on debt to sustain operations until they can demonstrate quantum computing's practical relevance [4] - Rigetti is currently raising capital by issuing stock to generate $350 million, which will bolster its financial position and allow for more aggressive investment in quantum capabilities [7] Financial Metrics - IonQ has approximately 16 quarters of cash remaining, while Rigetti has about 13 quarters left [7] - Free cash flow (FCF) is a critical metric for understanding cash burn, as it reflects operating cash flow minus capital expenditures [5] Market Outlook - Both companies anticipate that 2030 will be a pivotal year for quantum computing, with IonQ expecting profitability and Rigetti predicting significant market expansion [8] - They compete not only against each other but also against major tech companies like Alphabet and Microsoft, which have the financial resources to invest heavily in quantum computing [8][9] Competitive Positioning - IonQ has achieved a 99.9% fidelity in 2-qubit gate accuracy, while Rigetti stands at 99.5%, indicating IonQ's slight edge in performance [10] - The companies employ different technologies, with Rigetti using superconducting technology and IonQ utilizing trapped ions, which may present inherent risks in their respective approaches [11] Investment Strategy - A diversified investment approach is recommended, suggesting that holding a mix of quantum computing stocks, including Rigetti, IonQ, Alphabet, and Microsoft, may yield better long-term results than focusing on a single company [12]
