Quantum computing, a revolutionary technology, is capturing attention from both investors and tech enthusiasts alike. In a world where technological progress moves at lightning speed, quantum computing companies like Rigetti Computing and D-Wave Quantum are emerging as key players. Backed by promising market projections and significant institutional interest, these companies are driving innovation in this cutting-edge field.
Key Investment Trends in Quantum Computing
One significant development making headlines: Ken Griffin’s Citadel Advisors acquired stakes in both Rigetti Computing and D-Wave Quantum during the third quarter of 2025. Although modest in terms of position size, these investments reflect growing confidence in quantum computing’s potential to disrupt industries.
Rigetti Computing has seen extraordinary growth, with shares surging 3,750% since January 2023. Similarly, D-Wave Quantum’s shares have climbed 1,770% since January 2024, offering tantalizing opportunities for investors chasing transformative innovation in technology.
Understanding Rigetti’s Vertical Integration
Rigetti Computing operates with a unique vertical integration strategy, managing all aspects of chip manufacturing and cloud-based quantum software in-house. This approach gives the company greater control over its supply chain and enhances their ability to scale, especially as they push towards fault-tolerant quantum systems. Notably, Rigetti was the first to introduce a multi-chip quantum processor, showcasing its prowess in hardware innovation.
While the company has ambitious goals, including integrating 1,000-qubit systems by 2027, it’s worth noting that challenges exist. High valuations present a critical consideration, with Rigetti trading at a startling 1,080x sales ratio.
D-Wave Quantum and Its Unique Path
D-Wave Quantum adopts a distinct approach, focusing on quantum annealing technology as opposed to Rigetti’s gate-based quantum systems. Quantum annealing has been optimized to solve complex mathematical optimization problems, even though it has limited compatibility with broader quantum algorithms.
Currently, D-Wave offers systems exceeding 4,000 qubits and reported $3.7 million in revenue during Q3 2025, reflecting a 100% year-over-year growth rate. However, this expansion has been coupled with a rise in outstanding shares, which increased by 31% in 2025 alone, impacting shareholder value through dilution.
Market Growth and Projections
The quantum computing market is poised for a compound annual growth rate (CAGR) of 21% through 2030, signaling massive potential despite being substantially smaller than the artificial intelligence sector. Many analysts believe that mainstream, commercially viable quantum systems may still be one or two decades away. However, the progress of companies like Rigetti and D-Wave suggests that there are lucrative opportunities for early movers willing to handle volatility.
