Quantum technology firms race to market as the industry sees ‘inflection point’

Several quantum computing companies are braving volatile market conditions to list publicly through Special Purpose Acquisition Companies (SPACs) as the sector transitions from experimental research toward commercialization. Recent scientific breakthroughs in error correction and qubit scaling have prompted firms like Xanadu, Horizon Quantum, and Infleqtion to seek capital for scaling their operations. This shift marks a critical transition for the industry as it moves toward demonstrating practical quantum advantage within the next decade.

Xanadu Quantum, a hardware and software developer partnered with Nvidia, recently debuted on the Nasdaq and Toronto Stock Exchange following a merger with the SPAC Crane Harbor Acquisition. This follows similar moves by Singapore-based Horizon Quantum, which merged with dMY Squared Technology Group, and neutral atom specialist Infleqtion, which listed on the New York Stock Exchange. While these listings provide essential capital, they have faced significant market volatility; Xanadu’s shares fluctuated after its debut, while Horizon and Infleqtion have seen their stock prices drop by 18% and more than 30%, respectively, amid global economic uncertainty.

Industry leaders view this period as a vital inflection point driven by technical milestones achieved over the last 18 months, including improved quantum error correction and increased coherence times. According to Velu Sinha of Bain & Company, the industry is approaching a threshold of 100 logical qubits by 2028-2029, which could enable the first demonstrations of practical quantum advantage. However, larger-scale commercial applications in drug discovery and logistics—requiring 1,000 to 10,000 logical qubits—are not expected until the mid-2030s. Despite these long timelines, the total addressable market is projected to reach between $100 billion and $250 billion at full maturity.

To sustain investor interest during these lengthy development cycles, startups are focusing on near-term revenue streams through software and cloud-based services. Horizon Quantum is developing tools compatible with both classical and quantum systems, while Xanadu offers cloud platforms for developers to test algorithms on existing hardware. This commercial push complements long-standing government support from the U.S., China, and the EU, which have committed billions to secure strategic advantages. As Infleqtion CEO Matthew Kinsella noted, the public markets offer the necessary capital to accelerate commercialization in sectors where customer demand is already emerging, such as financial modeling and chemical simulations.
