Infleqtion, the Boulder-based quantum computing firm formerly known as ColdQuanta, completed its merger with Churchill Capital Corp X and began trading on Nasdaq under ticker QUBT on April 28. The combined entity carries a pro forma enterprise value of approximately $1.2 billion, placing it among the handful of quantum-focused public companies alongside IonQ, Rigetti, and D-Wave. Churchill Capital's trust held roughly $280 million before redemptions, which ran at 73%, leaving the merged company with $76 million in gross proceeds. The transaction closed without the PIPE common to most quantum SPAC deals in 2021-2022.
Infleqtion's revenue for the twelve months ending December 2024 was $14.3 million, derived primarily from government contracts with DARPA, Air Force Research Laboratory, and allied defense agencies. The company operates three product lines: atomic clocks for precision timing in GPS-denied environments, quantum sensors for magnetic and gravitational anomaly detection, and a cloud-accessible quantum computing platform with 32 neutral-atom qubits. The computing hardware trails IonQ's 64-qubit trapped-ion system but runs on room-temperature technology, a cost advantage in deployment.
The timing reflects a calculation: quantum computing remains pre-revenue at scale, but defense budgets now fund quantum sensing at production volumes. Infleqtion's atomic clock unit shipped 18 systems to undisclosed government customers in 2024, compared to 5 in 2023. The company's S-4 filing disclosed a backlog of $22 million, largely tied to multi-year sensing contracts. Going public via SPAC at this stage locks in capital before the 2025-2026 defense appropriations cycle, when quantum resilience provisions in the National Defense Authorization Act begin requiring fielded systems.
Allocators should track two events: the company's first earnings call as a public entity, expected mid-May, will disclose exact redemption impact and revised cash runway, likely 18-24 months at current burn. Second, the Department of Defense's Quantum Technology Roadmap, due for revision in Q3 2025, will signal whether neutral-atom platforms receive R&D funding parity with ion-trap and superconducting architectures. If neutral atoms stay in the roadmap's tier-two category, Infleqtion's path narrows to niche sensing contracts rather than broader computing platform revenue.
The SPAC structure itself is a tell: Churchill Capital X was the last unfilled vehicle from Michael Klein's 2021 vintage, filing for a sixth extension before this deal. No serious quantum company attempted a traditional IPO in 2024. The ones that did go public earlier—IonQ at $2 billion in 2021, Rigetti at $1.5 billion—now trade at $800 million and $150 million respectively, both below 50% of their debut valuations. Infleqtion enters the public markets with a lower starting multiple and a defense-contract moat, but the same unforgiving timeline: demonstrate $100 million in annual revenue within three years or face the same compression. The first data point arrives in fourteen days.
