Infleqtion has become a publicly traded neutral-atom quantum technology company after it finalized its combination with Churchill Capital Corp X, a special purpose acquisition company.
The company said Tuesday it started trading on the New York Stock Exchange under the ticker symbol “INFQ.”
Infleqtion CEO Matthew Kinsella said the company was founded on the belief that neutral atoms offer a scalable and economical path to commercializing quantum technology, and that its vertically integrated hardware and software stack supporting quantum computing and sensing has contributed to growing traction across government and industry.
“As a public company we can accelerate our technology roadmap and expand deployments in areas such as aerospace, defense and critical infrastructure, bringing practical quantum solutions to market at increasing speed and scale,” Kinsella added.
What Are the Details of the Infleqtion Transaction?
Infleqtion completed its merger with Churchill X, which was first announced in September.
According to Infleqtion, the transaction generated more than $550 million in gross proceeds, including nearly all of the cash held in Churchill X’s trust account prior to the redemption deadline.
The company also raised more than $125 million in incremental capital through a PIPE financing round, which included participation from new institutional investors and existing Infleqtion stockholders.
Infleqtion said it will ring the opening bell at the NYSE on Wednesday, Feb. 18, to mark its public listing.
What Does Infleqtion Do?
Infleqtion develops quantum computing and sensing systems using neutral-atom technology. The company’s portfolio includes quantum computers, quantum optical clocks, radio frequency receivers and inertial sensors designed for operational environments. The company also offers its Superstaq quantum computing software platform.
The company said its systems are already in use by the Department of War, NASA and the U.K. government, and that it has ongoing collaborations with NVIDIA.
In recent government-focused work, Infleqtion highlighted its partnership with NASA to fly a quantum gravity sensor in space, supported by more than $20 million in contracted mission funding. The company also cited a $2 million contract from the U.S. Army to apply contextual machine learning to enhance the service’s ability to deliver resilient navigation and timing capabilities, as well as its participation in the Department of Energy’s ARPA-E ENCODE program to apply quantum computing to energy grid optimization.
In June 2025, Infleqtion raised $100 million in a Series C funding round to expand its atom-based quantum platforms and accelerate the deployment of advanced quantum systems.
