Infleqtion

Infleqtion (formerly ColdQuanta) is a Boulder, Colorado-based quantum technology company that develops quantum computing hardware, quantum sensing systems, and quantum networking components using ultracold atom technology. The company's quantum computers use cold atoms similar to neutral atom approaches and can operate at room temperature in certain configurations, a potential advantage over superconducting systems that require cooling to near absolute zero. Infleqtion's quantum sensing products include atomic clocks and inertial sensors that provide GPS-independent navigation for defense and industrial applications — a near-term commercial market while quantum computing matures. The company also develops quantum networking components for building quantum internet infrastructure. Founded in 2007 as ColdQuanta and rebranded as Infleqtion in 2022 to reflect its broader quantum technology scope, the company raised over $100M from investors including Breakthrough Energy Ventures, Global Frontier Investments, and University of Chicago. It competes with Atom Computing and QuEra in the neutral atom quantum computing market while also serving defense customers with quantum sensing products.
