Infleqtion is a Louisville/Boulder, Colorado quantum-technology company — formerly ColdQuanta — that builds neutral-atom quantum computers, precision atomic clocks, and quantum sensors for governments, corporations, and research institutions. Its computing portfolio spans Sqale (a full-stack, fault-tolerant neutral-atom quantum computer), Quantum Cores (ready-to-use neutral-atom systems for laboratories), and Superstaq, an open-source quantum software platform with proprietary cross-layer optimization that compiles Qiskit, Cirq, and OpenQASM circuits down to hardware-native operations and routes them across heterogeneous quantum backends. Infleqtion's sensing portfolio includes the Tiqker optical atomic clock, Quantum Spectrum (Rydberg atomic spectrum sensing), and inertial sensors for GPS-denied positioning. The company was founded in 2007 as ColdQuanta, rebranded to Infleqtion in November 2022 after absorbing the Super.tech quantum-software acquisition, and became Infleqtion, Inc. (NASDAQ: INFQ) in January 2026. Superstaq (qiskit-superstaq, cirq-superstaq, general-superstaq) is the only developer-facing public surface; the hardware and sensing businesses are sold via direct engagement and government contracts rather than a self-serve API.
